Steps to Reproduce

1. Create a section(section A), with double click-Expand/Collapse Action on the Grid.
2. Configure another section(section B), which will display the Data of seleted Grid record .
3. In section B, include any section with Defer load configuration.
4. Run the parent section which contains both Section A and B, and double click on Grid record.

Root Cause

An issue in the custom application code or rules: The issue is occurring because of Expand/Collapse Action on the Grid. Because of this the particular TD on which event was triggered is adding isExpanded attribute to true.


Perform the following local-change: Add a Run Script Action on the Grid which will remove the isExpanded attribute. Add the function in any Harness level JS file or in UserWorkForm.

pega.u.d.KeepPageMessages = "true" ;
function resetExpandedFlag(ev){
var targetEle = pega.util.Event.getTarget(ev);
if(targetEle && targetEle.getAttribute("isExpanded")){
