SA-32949

Summary



The user is trying to join pyUserWorkList Report definition with work class properties. On the UI Screen, filters on pyUserWorkList columns are working fine but in case of blank values Null Pointer exception is being thrown on click filter icon for joined class properties/columns.
This is happening only in case of Blank values for joined table.

Steps to Reproduce

  1. Create a Report Definition(by joining pyUserWorkList)
  2. Create a DataPage and source Report Definition.
  3. Create a Repeat Grid and source data from above created data page.
  4. Check the filter on joined columns(other than pyUserWorkList columns).


Root Cause



A defect in Pegasystems’ code or rules. If there are no results in My Worklist of Case manager portal, results page is not getting populated on clipboard. Results page will hold the data of pxPages. On click of filter icon for joined property column, as the pxPages is not available on clipboard, Null Pointer exception is thrown.
