Tree Grid opens different thread in Clipboard on row click



Clicking a row in Tree Grid, creates new thread due to which user is not able to display data in UI.

Error Messages

Not Applicable.

Steps to Reproduce

  1. Configure a Tree Grid with a pagelist property as the source
  2. Source the pagelist property from a report definition by calling Rule-Obj-report-Definition.pxRetrieveReportData method in an activity
  3. Configure the Master detail editing and launch a flow action
  4. Run the flow. Multiple threads are created in the Clipboard

Root Cause

An issue in the custom application code or rules. 

The user has a work bound tree grid, that is, the report defintion that is used is in the Work class. As a result, in pzPerformGridAction activity bFromWork param is setting to true .
Hence, a new thread is created in the Clipboard.


Perform the following local-change: 

Change the source to Data class.

Alternatively, launch the local action using the open Local action method for the grid and check the 'Disable work processing' check box.
