Help with Session State Error When Making Items Read-Only in APEX Form

Inês Tomé29 hours ago

Hello,

I have a form in Oracle APEX with a Dynamic Action that sets values for several page items.

When I try to make some of these items read-only, I encounter a session state protection error, even though I’ve already gone through each item and:

  • Set them to Hidden
  • Disabled Value Protected
  • Changed their item types (some are Text, Date, and LOV)

I’ve repeated this process multiple times.

My goal is to make certain items non-editable by the user, but still allow them to be updated via Dynamic Actions — without triggering the session state error.

I also tried using Advanced → Custom Attributes → readonly="true", but that didn’t work either.

How can I safely make these items read-only to the user while still allowing Dynamic Actions to update them?

Thanks in advance!
