Application Express :: How To Fire Dynamic Action On Cascaded (child) Select List
Nov 8, 2012
When a user selects a Plan Type (Parent Select list) Plan codes (Child select list) to be filtered, working OK.
When a plan code is selected I need to do conditional display of regions.
Example: Plan code = A then display Region A
Plan code = B then display Region B etc.
I have a DA on Plan code select list but it's not working as it's being a cascaded (child) select list and the 'Change' event is already fired when I selected the Plan type, I also tried with other event options with no success.
im working with apex 4.2.1 and when i try to define a Dynamic action on any item, if the action type is "Set Value" or execute SQL/Javascript code it should appear a text field that let me define the action taking place. However this wont do..
this is what happens:
And this is what should happen:
I know that patch 4.2.2 solves some issues regarding dynamic actions but in the bug report there's no reference to such a problem.
I've been trying to use a dynamic action on a text field 'item_group'. Button doesn't have this facility. I created an advanced action using 'set value' with no condition the value being 'RAM.' The event is "change", selection type 'event source', set type is 'static assignment' and value is RAM. It is supposed to trigger when the create button is pressed but nothing happens and the field is still null. I've tried variations on this but nothing works.
I have a situation where I need to reference a hidden item in a List of Values (for a pull-down list) SQL statement. It doesn't seem to be working properly. Here is what I have:
1) Using a dynamic action, set the value of a hidden item based on the change of Select List 1.
2) Select List 2 has a parent LOV item of Select List 1, and the Select statement for Select List 2 uses the hidden item that was set from the dynamic action above.
I can see that the dynamic action is working correctly. But when I change Select List 1, the Select List 2 does not show any values from its LOV.
I'm wondering if the LOV for Select List 2 is not working because the item used in the SQL statement was set by a dynamic action?
I've created a change event dynamic action which fetches a description from the database for a user-entered code. When this is run in Firefox, a swirling loading image is displayed next to the description.However, the loading image causes anything displayed its right to be moved out and then back again when it disappears. On a form with lots of dynamic actions this can be quite disconcerting so I'd like to stop it.
Can a dynamic action's loading image be suppressed?
APEX inserts the following HTML alongside the input field: <span class="apex-loading-indicator"></span>One option is to apply "display: none;" to the "apex-loading-indicator" class but this could affect other loading images that use the same class.
I am using Apex 4.2. On a click of button a Dynamic Action is written, which calls a DB Package. The DB package has exception handlers and also the package has two output parametersError Code and Error MsgSo in my code(Dynamic Code) i make a call to the package and checks the value for Erroc Code.
Begin Package call...... If v_error_code <> '0' Then Raise SC_Error; End if;Exception When SC_Error Then RAise_Application_error(v_err_code, v_err_msg);End;
But when i run the page and I click I get an Internal exception errorOutput from Debug -- I am not sure what the Cell in Red colour means, because the package is returning a correct message (before the red line).AJAX call returned server error ORA-20003:

I’m on APEX 4.1, 11gR2, Windows 7 and the latest version of Firefox. I have an interactive report. I want the end user to have the ability to click on a row level link and launch a modal pop up view of another page. Ideally, I'd like to be able to use the Skillbuilders plug-in. I can get it to work if I just go the full page route but I cannot figure out a way to get it to work as a modal pop up. I’ve tried various methods, none of which work, but the one I believe I should be following is by using a page level Dynamic action that fires when a JQuery Selector found item is clicked. The problem I’m having is that I cannot find the correct JQuery Selector syntax for the column. My report has a static ID of IDN and my column a header of PARTS. The best I can manage is not to see anything happen other than a page refresh (when the link is set to the same page). I do not see and firebug console errors.
I’ve replaced the dynamic action modal page call with an alert, which is not showing, to make sure that it's not the plug-in configuration that is causing the problem.
what I should be filling in in the JQuery Selector field of the DA and what the link attributes should be? Given that I wish to redirect from page 1 to page 2, what do I put in the other link fields?
How to have a dynamic action populate text fields. When the create button is hit, it will insert the record in the DB like normal.
I had a search box doing a dynamic action when a record_number is entered and the selection changes It populates the remaining text boxes with the results of the record_number.
I used a "SET_VALUE" true action on each individual ITEM
For each individual item i have different SQL Statement populating that item.
Ex. To populate Last_Name/ P2_LAST_NAME item i do the following
Select LAST_NAME from patient_Demographics where record_id = :P2_RECORD_ID
Affected Elements: P2_LAST_NAME
So i have about 8 of these true statements, so i'm hitting the DB 8 times to get the individual items. Is there a way to hit the DB once and set the items using one PL/SQL statement? I tried using a PL/sql function body,
Is it possible to delete a row from a tabular form using dynamic actions.
At the moment my report sql contains html and javasript for a delete button
'<input type="button" name="Delete" value="Delete" onclick="del(''delete'','''||a.applicationname||''')">' A2I then have javascript in my page header function del(Request, Name){ var answer=confirm("Do you really want delete application "+Name+"?
* Provider assignments will be deleted * Application objects will be deleted * DB-roles will be dropped * DB-views will be dropped * User-synonyms will be dropped");
if (answer==true) { document.getElementById('P10_APPLICATIONNAME').value = Name; doSubmit(Request); } }
Finally I have a page process to do the delete which fires when the request = delete
for a text field of a, wizzard generated, tabular form i created a dynamic action when lost focus. using a jquery selector to bind the da to the item in every row when the event fires some jscript and pl/sql code is executed. this all works like charm for existing rows.
but how can i bind the da to the field for newly added rows?a sc of the definition of the da can be found here [URL]...
I have a select box with products, and a dynamic action that updates a display only element with the price, based on the product selection.After the selection is made and the page is submitted, I have noticed that the price is not stored in the database. If I change the display only value to a text box, the data is saved. Is this expected behavior? If so, can I add something to the text box to make it not editable?
i have a hidden region at the page top i want to show only after clicking my button which is running DA plsql code. This region is like a prompt message container/div at the top of the page so after few seconds like 10 secs i want to hide it again. I tried to use JQUERY but never hide it back, also i tried another TRUE CONDITION within my dynamic action but it doesnt reset it back the region is always shown...
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 have created a master detail form , in which many validation etc is done ,the MASTER is a FORM and DETAIL is a REPORTNow I am stuck up with the detail region .i.e reportI have Line Detail where there are ITEMS such as SL NO:
,ITEM_ID , UOM ( Unit of measuremnt ) etcNow here is where
Using POP UP LOV i have managed to fetch in LOV for the item "ITEM_ID",---
i can select an item name using the pop up LOV ,Now all that I want is when I select an item name from the pop up lov , an Item Id is displayed or fetched in that particular place , now i want the corresponding UOM to be diaplayed ( i.e the UOM for that particular Item Id which has been selected by me from the pop up lov ).
In order to resolve this I created a Dynamic action where in I get the UOM . Bt the problem is that the ITEMS displayed for selecting in the WHEN section (DYNAMIC action-IDENTIFICATION section-WHEN section----- items ( here i am not listed with ITEMS of the REPORT region instead ITEMS of the MASTER is available )-TRUE ACTION section etc is only theITEMS of the MASTER region ..
Event: click. type: jquery selector selector: a.show_popup no condition.
action: skillbuildersmodalpage 2.0.0 URL: attribute of triggering element.
This works fine, but after the popup is shown and closed, the link is not working until the page is entirely refreshed again.
after the popup is closed, i only refresh the report with $a_report , ( in another dynamic action on the "auto close skillbuolders" event) i don't want to submit all the page....the partial refresh is working fine too, but not the link, it only works again by refreshing or submiting all page
I have 3 pages: - Classes: a Classic Report that shows a list of classes and summarises attendance- Class Attendance Report: An Interactive Report that shows a row for each student that attended a class- Attendance Add / Edit Form On the Classes page, the Date value is a Link which passes a filter in the URL to the Class Attendance Report, showing only students who attended the class held on this date On the Class Attendance Report, I want to have a Region Button that, when clicked, goes to the Attendance Add / Edit Form and the Class Date field on this form is automatically populated with the same date value as was being used for the filter on the Interactive Report on the Class Attendance Report Page. So, I click on the Class Date link for 2013-11-01, this takes me to the Class Attendance Report and filters for students who have been already entered as attending on 2013-11-01. If I click on the "Add Attendance" button, it goes to the Attendance Add / Edit form and the Class Date is automatically set to 2013-11-01. I assume I need to do this via a Dynamic Action that runs when the "Add Attendance" button on the Class Attendance Report page is clicked?
I M USING APEX 4.1 AND CREATED SELECT LIST ON PAGE, I WANT TO SHOW MIN VALUE OF THE SELECT LIST FOR THAT I WROTE IN THAT SELECT LIST PROPERTIES UNDER DEFAULT TAG MIN; AND CHOOSE PL/SQL EXPRESSION BUT ITS GIVING ERROR "Error computing item default value for page item P1_PRODUCT."

BUT ITS NOT DONE LIKE THIS I WANT TO SELECT BY DEFAULT MIN VALUE OF THE SELECT LIST, SO THAT THE DATA SHOULD BE DISPLAYED ACCORDING TO THAT.
THE EXACT REQUIREMENT IS TO ENTER THE SELECT LIST DEFAULT VALUE IN SESSION SO THAT DATA IS TO BE DISPLAYED.

I am using Apex 4.1 and I have a select list in my page. I know i can access the value of the selected item by :P1_SelectList, but I would like to know how to access the display value of the selected item.
I have a 'Select List' widget (P_FILTER) which I have set to return multiple values. In my report region, I have something like this
Select A from B where B.Col_1 IN upper(:P_FILTER)
When user selects only 1 value, the report is correct but if user selects more than 1 value (e.g. 2), the report does not return any rows. How do I get the report to recognize the multiple values returned by the LOV?
I would like to enter input in for a select list. That is, if I have a select list for the common colours (blue, green, red, ... ) that a user could query on, then I would like a user to be able to type in the colour - purple in the box next to the select list. I've looked at the select list options and couldn't see anything obvious?
I have Select list itemS based on Lookup tables. When the form in Edit mode, I want to prevent the end user from changing the value of these Select list items. How can I accomplish this ??? **If I change the type of the item to Display only, then it will show the returned value of the Select list.
