A button controlled by when rule does not show to developer



When a section is included in a cell in another section, visibility rules are run. This means that, if you have a visibility rule that currently evaluates as false in a section, and that section is included in a cell in another section, the the parent section doesn't show part of the child section.

Error Messages

Not applicable.

Steps to Reproduce

  1. Create section 'A.'
  2. Set an element in section A to a visibility rule that evaluates to false at design time (for example, "1=0").
  3. Create section 'B.'
  4. Include section A in a cell in section B.

Root Cause

This is working as designed.  When a section is included in a cell (rather than as its own layout) some sections have a visibility rule which resolves to false.


An enhancement request has been created for consideration by Pega Product Management to change this behavior so visibility rules are not resolved when a section is included in a cell.
