Application Express :: Recognize A Change Of A Field Value?
Aug 21, 2012
I created a table (software defect details) and an interactive report on it. Users can go to the details form where they can manage many information: STATUS is one of them and they can change it or not.
I would like to send an email when SUBMIT botton is pressed only if field STATUS has changed. How can I detect this? I mean, I wrote a procedure in order to send an email and it works, but it runs always: I cannot set it running only when the content of STATUS_ID has changed.
how to understand if a field value has changed and, if possible what the old values was? I know how to do that by using a trigger (:old.status, :new.status) but I don't when using an APEX procedure.

I have a need to change the LOV of a page item's select list based on the selection in another page item's select list. So in other words, for a page item that is a select list, I need to use one LOV normally, and a different LOV if the value of a different page item is set to X.
A dynamic action would be useful here (on change where Select List 1 = x), but I don't know how to take the action of changing LOVsfor Select List 2 based on that action.

We are using APEX 4.2, 10GR2, RedHat5.
I have a report that comes from SQL Query (updateable report). I'm using the apex_item.text and apex_item.hidden on fields. I'm using a button to submit and after submit process to add some logic that I need.
There could be 1 - 10 records in the report. There is only 1 field that is needed to enter a value, but the value of this field determines the value of another field. I think that I can do this with a submit button and an after submit process where I loop through all the records. I think I have this handled.
This is the question
When the value of that field is changed then the value of another field in the same row changes immediately. All the examples I've seen so far are for a single record and that doesn't work for us.
I guess this is a MRU process but I haven't seen an example where a dynamic action is possible on a Multi Row Update.

I have an application item that receives a web service result. This result is like 'MARIA','JOSE','JESUS'. I'm using this string into the parameters of the interactive report, but this is not recognized. I'm showing the content of the application item into a pl sql region and the content is 'MARIA','JOSE','JESUS', when I include this application item into the query, the IR shows me 'MARIA','JOSE','JESUS'

Is there a way to change the Application Builder theme? There are themes for applications; how about for the builder itself? I looked but did not see a selection for this.
I'm a Geek thru and thru, I guess, but I think you might have to be xxxx retentive to like all these square boxes. And these old eyes have to squint to focus among the vast sea of gray shades.

I'm trying to make changes to a PL/SQL procedure in an application process and no matter what I do in the PL/SQL text (even removing semi-colons and messing up syntax) no changes register when I call the procedure from a page process. I've also tried creating a new application process with a similar procedure of a different name, and no page processes will allow me to call the procedure, saying that it needs to be declared. APEX 4.1.1

If it is possible in Apex 4.2 get interactive report where clause and change it before displaying result e.g. We have an report and for some of columns we should do exact match and for some partial match.And business requirement is that they should not add additional % at the and of search string. It should be added automatically for some fields.

I´m newbie as Apex developer using Apex 4.0 with OracleXE 11.2, and now my problem is:
I have a tabular form where one of the columns, when calling the form, is a Display Item, so that you cannot change existing values.
I want, when adding a new row, that column become a Select List (named LOV) based on a query that exclude existing values in other rows already inserted.
Can I change that Display Item to Select List (named LOV) programmatically at runtime? If not, what other options do I have?

In a detail tabular form I am referencing a date picker field from the master form as default value.This is the situation in the detail form:
TABULAR FORM
Column Name: FECHAREGISTRO -- the field's name in the detail tabular form
Default Type: Item (application or page item name)
Default: P68_FECHAREGISTRO -- It's a field in the master form and also is Date Picker format
Reference Table Owner: SAMPEDRORIVEROS
Reference Table Name: BITACORAABOGADO
Reference Column Name: FECHAREGISTRO -- It's a date field in the database
At execution time I have the error:
report error:ORA-01790: expression must have same datatype as corresponding expression
I think it is because i must use to_date and to_char in order to change the datatype and i have tried using:
Default: to_date(to_char(:P68_FECHAREGISTRO,'DD-MON-YYYY'),'DD-MON-YYYY')
and in Default Type: PL/SQL Expression or Function but I get a different message at execution time:
report error: ORA-01722: invalid number.

I am trying to change the column order in an Interactive Report. Run the report as a developer then use the action menu.
However, I am not sure how one can run the the report as a developer. Do you just login and run the page? Then if I do that, I don't see the action menu there. If I go to page attributes "Save Report" tab, I do see the action menu but "Select Columns" only gives me "Report Type", "Report Name" etc as columns. Or we don't have enough privileges to run the report as a developer?

I installed apex and configure the apex listener at port 80 by mistake couldn't pay attention to use port 8080. The installation is complete but the apex is running at URL.... but the login window is invisible on the page. I can just see the name on the tab "Application Express Login" . When i click on the error message at the bottom of the browser, the message says "apex is undefied" line 35.
When I run the server, I get a message "No free port within range 80. How can I change from port 80 to 8080? how to either un-install the listener or change the port 80 to 8080

I am using apex_mail (in Apex 4.1) to send emails with an attachment.
v_mail_id := apex_mail.send(
p_to => 'somebody@gmail.com'
...etc...
);
apex_mail.add_attachment( p_mail_id => v_mail_id
,p_attachment => v_image
,p_filename => 'signature.jpg'
,p_mime_type => 'image/jpeg');
Apex creates this as an attachment:
Content-Disposition: attachment;
I would like to change it to inline:
Content-Disposition: inline;
so I can reference it in my email body with <img src="cid:signature.jpg"/>. Well... I hope it is going to be shown inline anyway if I change Content-Disposition.
Currently (with Content-Disposition: attachment;) it works for Outlook, but, for instance, not in Gmail in the browser. Gmail shows the image separately as an attachment.
Is there a way to change the content-disposition with Apex?
I know it is possible to do it with utl_mail, but this is currently not installed in our databases. I need to involve our DBA to set this up, and I don't know if he is willing to do that.

Apex Version: 4.2.0.00.27Theme: 25 I have a page that I need to divide by 8 segments, rather than 12 ( I will need to place items and buttons in one of the 8 columns). To begin, I have made a copy of the One Level Tabs - No Sidebar page template. I have tried to edit this template, and played with multiple combinations changing the Grid Layout and Display Points settings, but instead of creating a page that has 8 columns, that span the width of the page, I am just left with blank space. See attached:.[URL] And these are the Page Template Settings:[URL] Is it possible to change the body section of the page template to have 8 columns span the entire width, without the dead space?

I have a problem with Tabular form. Configuration: Oracle 10g, Application Express 4.1.0.00.32.
I have tabular form on simple table. I need to change some column values before MRU. For example: i have column named "UPDATE_DATE" where i need write SYSDATE every time this record was updated. I've created page process, associated with my tabular form.
Process point: On Submit - After Computations and Validations;
Sequence set to 1 (before "ApplyMRU" process - it has sequence 10);
When Button Pressed: Submit;
Execution Scope: For Created and Modified Rows;
Source:
declare
indx varchar2(255);
l_map wwv_flow_global.vc_map;
l_id number;
l_pk number;
begin
[code]........
But this doesn't work. MRU process writes old values, that was posted from browser. I tried change values by
apex_application.g_f04(:APEX$ROW_NUM) := sysdate;but this also not work.
How can i change values before MRU? Why wwv_flow_tabular_form.set_row_values doesn't change values?

I am having a problem with a popup lov. When I click on the "popup icon" I can select a supplier and it is stored in the field. But when I leave the form and return later, it shows the return value instead of the display value. For example: you select "supplier A" from the popup list with ID 12. "Supplier A" is shown in the text field, when you save the form, it stores ID 12 in it. But when you return to the form, it fetches ID 12 and shows "12" in the text field instead of "Supplier A".
I tried setting the "source" of the popup lov field as an SQL query, but that didn't work for me.

Let's say that we have an order entry app and the price and quantity items are already populated. We now want to show the user the extended price (the product of the first two items). the extended price would automatically display after both the quantity and price items are entered. I'm assuming that would require some kind of client-side processing. I imagine server-side processing is simpler, so I'll lean in that direction. I'm sure we've all seen web sites that require you to click a button for the order totals to be updated. I'm okay with that approach, but I haven't quite put all of the pieces together. Here's what I came up with.
A region button was added to trigger the updating of the extended price. The button's "Action When Button Clicked" is to submit the page. Under "Page Processing", a process was created to do the calculation with the recipient of the product being a page item. From debug code in the procedure, I can see that the item containing the extended price was, indeed, modified. But the new value doesn't display in the field and the Session window shows that the value of the item didn't change.
I must be missing something. The debug code says the item value was updated. The Session window says it wasn't updated. What gives? What did I do wrong and what needs to be done to correct this?

i m using Apex4.1 and data base oracle 11g, browser firefox
i m using recaptcha plugins i had tried it with both way by creating 3 hidden field and and also directly with taking a item based on plugin. URL.....
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 redirect to another page. The problem I'm running into is that the text item is always submitted regardless of the captcha.

I am using APEX 4.2
I have created a form with a Date From and Date To fields.
I am using the Date Picker format (the new one, not the Classic), and have set the calendar to Show on Both (Focus and Icon Click).
I would like to restrict the field so that the user cannot enter any text - they can only use the Date picker/calendar to choose a date. This would them remove the clunky validations - so I can restrict the users so they can't enter the wrong format in the first place.
Is this possible?
