Declare expression fired unnecessairly



Every time a page changes(even upon instantiation of the page or setting any property page ) , the declare expression is fired even though the declare expression rule is written as a sum of “.<INITIAL PAGE>.<SUB PAGE>.<PROPERTY>”.

Error Messages

Not Applicable.

Steps to Reproduce

  1. Launch the Pega portal.
  2. Create a repeat grid with the page name reference alone.
  3. Load that newly created page into UI.

Root Cause

The root cause of this problem is a defect in Pegasystems’ code/rules.


This issue is resolved through the following  Local-change:

Create a when rule condition which returns false if .secondary page list is empty. Add this as pre-condition in the declare expression.
