Application Express :: Conditional Read Only That Saves To Database?
Nov 27, 2012
I have an item that does not save to the database.it is conditional read only based on the value in another column, when it is not read only it displays as a Select list.. then whatever is chosen triggers a dynamic action that sets other items.so setting it as a display only is not an option.
after upgrading from 4.0 to apex 4.2 this gives error: Session state protection violation: This may be caused by manual alteration of protected page...
the only workaround I have found is to set the Read Only to none, then create a dynamic action that conditionally sets the field to disabled..This works, but my problem with it is that it looks different than the read only..read only was Black Text and no textbox..disabled is a text box with greyed out text that is hard to read for some of the users..

Is there any way I could set the condition on the list of values.
For example if Value of the item x is null then use select ...
and when value of the item x is not null use this select ....

Is there a way to make a button conditional on the existence of another app in the same workspace. What I am trying to do is have a MAIN app and several other MODULE apps in the same workspace. Then a button on a form in the MAIN app that will redirect to a specific page in one of the MODULE apps. If the MODULE app does not exist, meaning not installed, then the button would be invisible.

I implemented the re Captcha plugin and it works ok. What I want to do is, on the same page where the captcha is displayed, to have a report region that is displayed conditionally based on the captcha result.
More specifically, the page has two items for user input (the captcha and a text item) and a Submit button. If the captcha is successful, then the text item will be submitted and the region displayed. The problem I'm running into is that the text item is always submitted regardless of the captcha.

Apex 4.2I currently have a report column in a classic report that has a Column Formatting Attribute as below. This works fine it shows a map icon that when you click on it goes off to google maps and put 2 geo points on a map. However I need to change this report column so that the HTML expression will be different dependent on the value returned so if the column returns 1 then the HTML Expression will be slightly different.
HTML EXPRESSION <span class="map_#BROKE_GEO#_#VALID_GEO_CODES#"><a target=_blank href="f?p=&APP_ID.:323:&SESSION.::::P323_PARCEL_ID,P323_SCAN_ID,P323_PROP_ADDR1,P323_PROP_POSTCODE,P323_PROP_LAT,P323_PROP_LONG,P323_SCAN_LAT,P323_SCAN_LONG:&P341_PARCEL_ID.,#SCAN_ID#,#LINE_1#,#POST_CODE#,#PROPERTY_GEO_LAT#,#PROPERTY_GEO_LONG#,#SCAN_GEO_LAT#,#SCAN_GEO_LONG#"><img src="#WORKSPACE_IMAGES#&P341_IMG_MAP_#BROKE_GEO#." alt="Google Maps" title="Google Maps"></a></span>
I think I can do this in the report source directly with a case statement and include the HTML in that for the column but how do you handle all the quotes within the SQL statement. e.g.
Original Query SELECT parcel_id ,status ,LOCATION ,scan_date ,scan_id ,driver_comments ,card_id ,valid_geo_codes -- this is my html column ,property_geo_lat ,property_geo_long ,scan_geo_lat ,scan_geo_long ,broke_geo ,line_1 ,post_code FROM vw_parcel_history_details WHERE parcel_id = :p341_parcel_id ORDER BY scan_date New Query SELECT parcel_id ,status ,LOCATION
[code].....
various iterations of that large html string but I do not know how to format it because off all the quotes?

For our customer we have build a custom login page. The form we currently made has de following items:
- Username
- Password
- Select list for selecting the task type
When the customer enters his username, automatically the select list of the task type will be refreshed to get only the task type where the customer has the rights to do it. This part works...It can occur that a customer has only one task type (which is default) then we want to hide the select list. This part doesn't work
We used APEX version 4.1.1.What we did is:
- One action item to refresh the selection list (works)
- One action item to hide the selection list by starting the application (works)
- One action item to show the selection list only when the selection list has more than one result. For this part we used the conditional part of the action item (Function returning a boolean).
In the query (inside the function) we want to use the entered username, looking into the application in the session state I saw the correct username, but for some reason the function cannot use this entered username, it becomes empty. When I use a hardcoded username the code works.
Why I cannot use a username into the conditional part of the Action Item.

I had a few regions on my page, the 2nd did not start a new row so it appeared horizontally where possible.During some experimentation, I created a new region with a sequence in between that started new row, but even when that region was conditionally never, my original 2nd region started on new row.
Original:
Region 1 - Region 2(empty) - Region 3 (new row/col no)>
New region added:
Region 1Region 1.5 (added, new row)
Region 2
Region 3>
Region 1.5 not shown:
Region 1Region 2
Region 3>
Let me know if you would like a test case for better visualisation.

We have an issue after migrating to apex 4.2.1. We have a select list and use another couple of dummy items to be used as its label instead of giving the text value to the LABEL control. Only one of the dummy items is shown as a label for the select list conditionally based on another value. It was working fine with the earlier versions upto 4.1, but with the introduction of grid in 4.2, its now displaying the select list on a new row (ie the lable in one row and the select list on the next row).
However, we really would like to solve this by having a way to display the label of the select list either in "required format style" or as an "optional style". The display style should be determined only at runtime.
Example. Say P100_MY_SELECT_LIST is the select list
The label for this item is "My Select List Label"
I have another dummy item P100_DUMMY
if P100_dummy = 1 then the label "My Select List Label" should be displayed in red and with an * *My Select List LabelOtherwise it should be in black and without * My Select List Label.

We have integrated Oracle Access Manager 11gR1 with Oracle Apex 4.1. The OAM-Apex integration is working fine. Now we want an additional header variable to be passed from OAM to the Apex application. This new header variable will be user's sAMAccountName in Active Directory. OAM is integrated with AD and the AD users are successfully able to access the Apex applications.
The three header variables which are configure in OAM right now are:
Header variable name Value
1. OAM_REMOTE_USER $user.userid
2. OAM_REMOTE_USER_EMAIL $user.attr.mail
3. OAM_REMOTE_USER_GROUPS $user.groups
We need an additional header variable as mentioned below:
Header variable name: OAM_SAMACCOUNTNAME
Value: $user.attr.samaccountname
The new header variable was added in the OHS server's dads.conf file like shown below:
=========== dads.conf =============
...
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_GROUPS
PlsqlCGIEnvironmentList HTTP_OAM_REMOTE_USER_EMAIL
PlsqlCGIEnvironmentList HTTP_OAM_SAMACCOUNTNAME
But we are not able to read the value of this attribute in the Apex application.On the Apex application, we have a text box which shows the value of this header variable. This textbox is attached with the following stored procedure call to fetch the header variable:
===================
begin
:P1_HEADER_VALUE := owa_util.get_cgi_env( 'HTTP_OAM_SAMACCOUNTNAME' );
end;
The textbox shows the correct value if HTTP_OAM_REMOTE_USER is passed to the get_cgi_env method but does not shows anything when HTTP_OAM_SAMACCOUNTNAME is passed to the same method. if I am missing some configuration to pass the HTTP_OAM_SAMACCOUNTNAME haeder variable from OAM to Apex.

I had a situation last year where I could not login as myself or see any objects in my schema. Some code using APEX methods to create a new APEX user, and it finally worked.
The new user, ADMINUSERS suddenly had its password expire and I could not reset it, so I repeated last years’ effort but this time nothing worked.
Now I have a problem where I cannot even read a table if it is in another schema, even if I use the schema name as a qualifier. This happens even in SQL plus, except when I login as System I can read tables in other schemas if I prefix the table name with the schema and a dot. But this does not work with other users, even though I have granted the other users the role of dba.

i encountered a big problem after upgrading Apex from 4.1 to 4.2.2. On an application page there is a Text Area which will be read and processed after clicking a button. I didn't want a refresh of the page and did it with a dynamic action.All this worked like a charm with 4.1. Since the upgrade, the value of the Text Area is always returned as null while processing the dynamic action, but the value is filled by the user!When i change the type of the Element to Rich Text Area everything works fine, but i don't want this because i don't want HTML in the corresponding table. Is this a bug? How can i workaround it?

When we upgraded the database from 10g to 11g, Apex upgrade failed. Due to the failure, I removed the old schema and did a fresh install of Apex 4.1. It is working but we lost the applications from previous Apex.
What is the best strategy when you need both database and Apex upgrades? We are a Linux workshop, setting up Apex in Oracle Fusion Middleware 11g environment.

There is a report that is generated everyday in the .csv file format that i would want to load into the database. I want to completely automate this process. I don't want to use the load function available in APEX. I use APEX 3.2 Version.
What i mean by automation is that i will create the CSV file and automatically move to a location from which APEX can access the data. I would then write a procedure to fetch the content directly from CSV file and write to the database. What i need is the location from which APEX can access data directly ?

Does version 4.2 create a new db session for each report run on a page?
The reason I ask is we have a page with 4 report regions, each querying a global temporary table that is populated in a 'Before Regions' page process. The first report displays the correct data, but the others return 'No Data Found' and it is because the Global Temporary Table has been cleared out following the first report. This did not happen in 4.1.
I know we should be using Apex Collections, and we will in future, but time is at a premium to get this live

I'm using Application Express 4.2.1.00.08
In the application, the authentication method used is the DB one, so the user (schema) must exist on the DB. This works fine.
For instance, I'm login as SCOTT
Creating the following query select upper(user) from dualshows that the real logged user is APEX_PUBLIC_USER and npot SCOTT.
How to create a connection with another "real" username ?

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!
