title: Set display value of text field on change of other text item in Oracle ApEx
body: <p>I have an Oracle ApEx (version 4.2.5) database application with 1 "Home" type page displaying the current records in a table and a "DML Form" type page where you can insert/update/delete records to the same table. That is a generic "Report and Form" type application.</p>
  
  <p>On the 2nd page, I want to set value of 4 text fields on change of a specific text field named P2_KOD. For that, I have created a dynamic action regarding that specific text field. I have set event to "Change", selection type to "Item(s)", item(s) to "P2_KOD" and left condition null (ie. "- No Condition -").</p>
  
  <p>Then I have added a true action to set values of 4 text fields. I have tried "Set Value" actions of both "PL/SQL Function Body" and "JavaScript Expression". But I could not manage to set display values of that 4 text field. I know that I can set the session values of that 4 text field since I see them in "Inserted" state with correct item values assigned in the "Seesion" info.</p>
  
  <p>What is wrong with my configuration?</p>
  
  <p>Edit#1: I have created the same scneario on apex.oracle.com. You can login with the following credentials and check out the "Application 76791 - Simple Rep &amp; Form App". There is a dynamic action named "WHEN_DEPT_CHANGED" which should change the value of P2_COMM to 3 times the value of department.</p>
