Steps to Reproduce

  1. Create a Grid Repeat Layout in a section.
     
  2. Configure the layout. In Operations tab > Row operations >  Display of details > select 'Expandable rows' . Check the option to "Enable displaying details on multiple rows".



    ​
  3. Configure a custom Data Transform or an Activity on the Flow Action which is calling the particlaur section.




     
  4. Set the pyExpanded flag to true (setting this flag programmatically in activity or data transform rule)




     
  5. The row expands and sets this flag programmatically.

Root Cause



Without "Enable displaying details on multiple rows" being checked, system does not allow modifying row level properties from Activity or Data-Transform.
 

Resolution



This is an expected behavior. To make sure, that the rows expands using pyExpanded check the correct page in the clipboard under pyWorkPage.
