pxCaseMgrScript JavaScript does not work with a Screen layout



pxCaseMgrScript is used in the Scripts and Style tab of the harness which has a panel set in it. With the panel set, the review panel expands onClick of any record in the grid. However, when the panel set is converted to a screen layout, the script does not work.

Error Messages

Error in browser console: 

Cannot read property 'layoutObj' of null.

Steps to Reproduce

  1. Create a harness.
  2. Add a Footer screen layout with a grid.
  3. Add the pxCaseMgrScript script in the Script and Style tab.

Root Cause

A backwards compatibility defect in Pegasystems’ code or rules.
The pyCMCases and pxCaseMgrScript sections were designed earlier and support minimum features with some limitations.


Perform the following local-change:

Use a custom script file in the pyCMCases harness' Scripts and Styles tab to set the footer height.

Replace this code:

 if (pega.util.Dom.isAncestor(gridDiv, target)) {

with the below code.

if (pega.util.Dom.isAncestor(gridDiv, target)) {
