Modal Flow Action hangs on submit

SA-15590

Summary



When a Local Modal Flow Action is defined with a Repeat Grid and Expandable Rows are defined with the “Enable displaying details on multiple rows” flag checked off, the modal flow action will hang after submitting, if there is a validation message.


Error Messages



Not applicable.


Steps to Reproduce


 
  1. In the PegaSample-Task class, create a Section Rule with a Repeating Grid which references a pagelist
  2. On the Operations tab, set the “Display of Details” to “Expandable Rows”
  3. Add a flow action to display in the expandable row. This should contain editable properties in the pagelist.
  4. Ensure that the “Enable displaying details on multiple rows” flag is checked off
  5. Create a Local Flow Action to contain the section created in Step 1
  6. Add a simple validation rule to the Flow action, e.g. pagelist input field must not be blank
  7. In a General Task section rule, create a Link which runs a Local Modal Flow action to reference the rule created in the previous step.
  8. Use “Create“ menu and select Case/General Task
  9. On New Harness click the “Open Local Modal Action” link
  10. On modal popup, click “Add Item” and then submit without entering any data. This should result in an error
  11. Click on the blank first row of grid to expand and enter some data
  12. Submit the screen again and observe that the Modal Action is no longer responsive and the submit does not happen



Root Cause



This issue is due to the nested flow action. When a nested flow action is opened properties in "newModalPage" are overridden. This is a known product limitation.
 

Resolution



An enhancement request has been created for consideration by Pega Product Management.
 

A local change is to check the "Enable displaying details on multiple rows” flag
