Question

Hello,
I have a need where based on the contact method the time zone field needs to remain grayed out.
For e.g. in the code snippet below, if user select pref_method as 'EMAIL' then the TIME_ZONE field needs to be UPDATE NOT ALLOWED.
If the user selects "PHONE" then time_zone method can be updateable.
The problem is; following code is not working. It grays out the timezone field when user selects EMAIL, but still user can navigate to the TIME_ZONE field and update.
What am I missing?
currec number := SYSTEM.CUSROSR_RECORD;
if :block_account_contact.pref_method != 'PHONE' then
         Set_Item_Instance_Property( 'block_account_contact.time_zone',currec, UPDATE_ALLOWED, PROPERTY_FALSE);
         Set_Item_Instance_Property( 'block_account_contact.time_zone',currec, NAVIGABLE, PROPERTY_FALSE);
         Set_Item_Instance_Property( 'block_account_contact.time_zone',currec, VISUAL_ATTRIBUTE,'ITEMPROP');
   end if;Thanks,
R

Answer 1

What kind of item is PREF_METHOD field ??
If it is a text item try the same code in the WHEN-VALIDATE-ITEM trigger
if this is your code is not well written, it should be :SYSTEM.CURSOR_RECORD
currec number := SYSTEM.CUSROSR_RECORD;
