Application Express :: Clearing Cache From Home Link
Sep 29, 2012
I am using theme 4, topaz. Region_Position_06 is a home link.
I have placed a company graphic at this position on page zero, and when a user clicks it on any page, she exits that page and goes to the home page, a main menu page. So no matter how deep a user may be into the application's pages, she may always click this logo image and return directly to the main menu page.
This is convenient, but there is one problem. Clicking this logo does not clear the cache on the page the user is exiting or, for that matter, on any page in the trail of pages the user took to get to the current page. I navigate primarily with buttons and always clear the cache on a page when I exit it. I need to find a way to do this when a user clicks the logo image.
I understand everything -- <gripe> need better Automated Row Fetch (ARF) documentation </gripe>, but I now have CREATE, QUERY, and DELETE working and I can choose to clear the form (or NOT). And I don't claim this is the best or simplest or most-efficient or most straight-forward approach. It's one virtue is that it does seem to work.
I need to be careful state that this involves both Automated Row Processing (ARP) -- which enables INSERT, UPDATE and DELETE. And Automated Row Fetch (ARF) -- which enables SELECT. ARF is found under Page Rendering and ARP is found under page processing. As we have seen, the two are -- or can be -- interdependent. For example, I believe the error I talk about next is caused by ARF trying to fetch the record just deleted by ARP.
Starting from the situation of
1) having the values retained on the screen when CREATE is clicked and the record is added and 2) getting a database error after a DELETE of a row, A solution is the "reset" processes. Under Page Rendering add a "reset page" process to: "Clear Cache for all Items on Pages (PageID,PageID,PageID)" and indicate the page with the database operations and under Conditions: When Button Pressed: choose CANCEL, CREATE, DELETE, QUERY or SAVE. I made two of these - one for CREATE and one for DELETE. To cover both buttons, you need two processes as you can only indicate one button per process.
Now the form (screen) is cleared after the CREATE (by process 1). And since it's also cleared after the DELETE (by process 2), there is no Database error on DELETE.
(The source of that error was ARF trying to retrieve the deleted record because the PK field had the "just deleted" key value. This nulls it and I have ARF set not to attempt a fetch when the key field is null.
So, how about that? Burleson has an example here which adds more detail than I recall seeing before.URL>....
I think the DML Fetch Mode settings he shows are new to the ARP screen in 4.2. I don't see them in 4.1.
I've created a new appliacation which has a home page and I've created a report page which updates a table. I want to add a link to my homepage, as a text line for example UpdateTable, and when I click the link, it goes to my report page. I've had a look in my Apex CookBook, and it says I do this by using the Navigation region in my home page. The problem is I don't seem to have a navigation region in my home page. I thought initially it meant the navigation bar, but I now realise this is the header bar. Do you know how I can create a navigation region in my home page..?
Statuswhen they entered the details and submitted the form the data will be stored in LEAVE table. later on the applied leave will be approved or rejected and the STATUS column will be updated. Is this possible to show the last leave applied status as a alert message when they are logging in ?
I have an application built in Apex 4.2It's been running fine for several weeksI've not made any changes to the codeSuddenly it developed what seems to be a cache problem.If I enter a search criteria; it displays results. I enter a different search criteria and it brings back the same results as the first criteria.I enter a search criteria in a different field and I still get the results from the first searchI go from Internet Explorer to Mozilla.
DIfferent search criteria, but same issue. Google chrome - same issueThe obvious answer is to clear the cache.I have a process set up that is clear Cache for Items , on submit after computations and validations and then I list all the items individually.This process has been there all along.
I never had this problem before.If I log out and come back in, same issue. What ever I enter as the first search criteria is the results no matter how I search
i have created form with table page to enter hotel details there is on 6 check box which are not database column .i have create these check box to keep days details when hotel give service .so i have use
these 6 check box are used Source used :Only when curren value in session state is nullSource Type : Static Assignment (Value equals source attibute) Problem are when i create new record then these 6 check box are not clear cache and when i update any record value are not clear cache . i need when i create or update recor then all 6 check box should be null after keep recor.
APEX 4.2.1 On a page with dozens of editable page items, when branching back to the same page on-submit, is there a way to clear cache for all items except a few (key) items? The branch attributes (via the f?p= syntax) support clearing cache for the entire page and setting specific item/value pairs but no support for exclusions.
We had several unexplained lock-ups of APEX in our environment in the last months. This all happened after we moved to GlassFish with the APEX Listener. The symptoms were always that all connections in the JDBC connection pool were in use and we had to restart the GlassFish server instance to free them up.
The culprit is the caching folder that the APEX Listener uses for file caching. We use this to cache image downloads from the database through a procedure, and the caching folder was set to /tmp/apex/cache. I believe this is the default setting. All went well, when the procedure was called the images were downloaded from the database and cached under /tmp/apex/cache. However, for some (as yet unexplained) reason, Linux sometimes removes this folder from the /tmp file system. This seems to happen from time to time after an unknown period of inactivity. We didn't reboot the server. After the folder is gone, the APEX Listener is unable to recreate it, keeps on creating new database connections until the maximum configured is reached, and we need to restart the GlassFish instance to free them up. This also recreates the caching folder.
Our environment: GlassFish 3.1.1+3.1.2, APEX Listener 1.1.3, Oracle Linux 6.2. I didn't try out the new APEX Listener 1.1.4 yet so I'm not sure if this has been fixed in the last version.(kind of reminds me of the problem where the APEX config file is by default placed under /tmp and also disappears from time to time)
i want to disable my EDIT link in report if it satisfy my case condition.
i am using some code but using this i can unable and disable text link not a image link how can i disable image link like edit link in report.
select * from ( SELECT AP.*, CASE WHEN AP.INVOICE_STATUS='C' THEN '<font color ="Red"></b>Modify Invoice</b></font>'ELSE '<a href="f?p=&APP_ID.:58:&SESSION.:INV_ID:&DEBUG.:58:P58_INV_ID:' ||INV_ID||':"> [code]........
I have IR wit one column link target to URL, and it uses javascript:my_function(#COLUMN_VALUE#)as URL, that is, calls some function and passes the value of that column to the function; everything works fine; but when I place a cursor over the link, bottom line of IE9 browser (is it called a 'status bar'?) clearly shows:
'javascript:my_function(<actual value>)' Is there any way to prevent it from showing function name and parameter value? I tried onmouseover="window.status='';"but it does not work
I'm a APEX newbie using APEX 4.1. I have a table with engineering drawing information (drawing number, title, revision, etc.) and another table with the corresponding drawing files (pdfs stored as blobs where the filename is the drawing number with a pdf extension). The user wants to search for a particular drawing by drawing number from the drawing info table and if the drawing number exists in the drawing files table the drawing number will also be a download link for the file, if the drawing number doesn't exist in the drawing files table than the drawing number will display as plain text (not as a download link).
I have a report linked to a form. The link column is currently ROWID and I want to change it to the Primary Key of the DB table, which is called ID.
I have done this before on a previous report/form where that ID was a display column and it works fine. Now I'm trying to copy what I did, which is this:
On the report page, go to Interactive Report attributes, scroll down to Link Column, and for Item 1, change the Name and Value.
The problem is that Name does not list P52_ID. If I type it in, it throws an error when I run the page.
I think I added ID, which is also a Display column, later on, so I wonder whether Apex has a refresh issue and can't "see" P52_ID.
I have an Interactive Report with a column that I need to create a link on but I need to pass the value of another column.
This report shows the Features of a particular Release. There is a select list for the Release that is selected and executes the report. There is a column that indicates whether the Feature has a Commitment attached to it. If there is have that a link to another report that shows all the Commitments for that Feature by passing the FEATURE_ID which is also a column on the Feature report.
Query: SELECT .... ,CASE WHEN ft.feature_id IN (SELECT cc.feature_id FROM customer_commitments cc WHERE ft.feature_id = cc.feature_id ) THEN 'Yes' ELSE 'No' END "Commitment Exists" ,ft.feature_id ....
FROM ....If "Commitment Exists" has a 'Yes', the 'Yes' is a link that will pass the FEATURE_ID to another report that will show the Commitments for that Feature. If the "Commitment Exists" has a 'No' then no link. I was also wondering if the Commitment report could open in a seperate window and make it modal?
I have a question regarding db link. I have a query that uses a database link, i speed it up by adding the DRIVING_SITE hint and it worked when executed from
sql*plus or pl/sql developer.
It returns results in 3 seconds or even less. However, when i put this query back into the APEX application, specifically into an interactive report page -- it runs for 3 mins!
I have an apex page with a link on one column for each row. My requirement is as below
When i click on the first time on any of that link, it opens up in a new window and any subsequent clicks should override the previously opened window. So at a time, there should be only 2 windows open..
1) the APEX page 2) The browser window after clicking on an link in apex page
I have a requirement where users will select an instance (db link) from an apex LOV and the data in an interactive report will query based on the db link selected. I can use a db link in an interactive report query but only if I provide the exact name of the link. If I do something link select * from foo@:P12_ DBLINK it doesn't work. It seems my only option is to use something like apex_collection.create_collection_from_query and then I can build my query with dynamic sql and use a variable for the dblink name. Then I just create an IRR based on my collection. Does that sound like that correct approach and/or am I missing anything?
Apex 4.2.0.00.27 I have a page with a Form region and a Classic Report region. How can I automatically save changes made in the Form when a user clicks the Edit link column in the Report? At the moment, when the user returns to the Form, any changes made there are lost.
I Have an apex page that display a modal window utilizing jquery. In the modal window I have a classic report with a link column that I want to capture its click event.
I was thinking I could create a dynamic action with selection type=jquery selector. Not for sure if I need to do anything on link column and do not know the syntax jquery selector.
I go to Report Attributes, then I click Add Column Link in the "Tasks" right menu, it adds me a column link, I just add some text for the link and a page to go to. Then I run the report and I get :
report error: ORA-01403: no data foundTested with several classic reports on multiple pages.
Debug mode shows me :

On my APEX page i have region which has sql query as source and it displays as HTML table the query result to the user.
I want to display addinonal column with a hyperlink inside, and that hyperlink would have CGI/URL-parameters which contains the other values of the HTML row.
So, let's say my APEX region queryes columns as "select c1, c2, c3, c4 ..." and displays out values "V1, V2, V3, V4" then i want to have addional output column with such hyperlink:
a href="f?p=100:7:13467554876288::NO::c1,c2,c3,c4:v1,v2,v3,v4">My link column with CGI-parameters</aHow can i create such hyperlink?
The overall idea is that the link would forward to a page which loads those values "v1,v2,v3,v4" into form fields and user can proceed from there.
I have a query that selects multiple series for a bar chart (I have defined only one chart series, and have 3 columns selected to represent 3 series). The series display on Bar Chart is fine. Now I want to create a separate link target depending on which series is clicked on the chart. I am not able to do this.
I'm looking for a solution to hyperlink to a local file (i.e. C:/test.txt). I want that the user clicks on a "browse file" button like the file browse item. after the user selected a file or just a folder the path should be shown in a display only item. this item should be clickable...
Is it possible to create a "Browse file" dialog? I know that to link to a file is possible with some HTML tags in the "pre element text" and "post element text" fields. something like "<a href="... but I don't know how this works.
We are using Oracle 11g with Apex 3.2 on AIX. We are reporting data from customer satisfaction surveys. I'm using the following sql to create my report
<code>select * from( select month,'Overall Satisfaction' as q_group, 1 as srt,Overall Satisfaction,site, case when count(*) < 31 then '*' else round((sum(ttos)/count(*))*100,0)||'/'|round((sum(bfos)/count(*))*100,0)||'/'||count(*) end ospct from v_XXX_report a,(select distinct month_dt month from v_XXX_report) b where Overall_Satisfaction is not null and year_dt = 2012
[Code]....
The problem is that site is not allways present and sometimes I have other variables in addition to site. This creates a situation where the month columns will not allways appear at the same column number. For example, When I run this query as is then the "JAN" column is Col3 (first column is a break, col2 is not shown). When I run this query without site then "JAN" is the second column. I would like to create column links for the "JAN" - "DEC" columns but not for any other columns.
Another issue - in the column link creation screen I can create up to 3 variables that I can pass to the next page. Since my query is a pivot I'm uncertain how to pass the column heading or the row value (for col2)
ie Overall Satisfaction JAN FEB MAR APR MAY ... Overall Satisfaction 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240... Recommend 12/12/200 12/12/210 12/12/220 12/12/230 12/12/240... etc.
So if I clicked on the values at Recommend:FEB how can I get "Recommend" and "FEB" into variables that I can use on the next page? I've tried #column_name#, #month#, #q_name# and #APEX_APPLICATION.G_F10# but no luck.
I want to pass multiple column values of a row in an interactive report page to hidden items in another page through column link. And I did it successfully. However, I found I need to pass more than 3 columns of a row in this report, while a column link only permits me to pass 3 column value at most. Is there anyway that I can pass more column values to hidden items in another page?
