Error Messages

Not Applicable

Steps to Reproduce

2.Run case.
3.Observe when source page has only one value, then list is empty in UI.

Root Cause

A defect in Pegasystems’ code or rules:

While preparing list of UI elements , there is a check in listtolistjs API as:

if(this.aSource.length == 1 && this.aSource[0] && typeof(this.aSource[0][this.sDisplayProperty]) =="undefined"){

Here if sourceObject.display property is undefined and source list length is one, then it removes the object from source.
In this case display property is AccountID and object has property as AccountId, so if condition is true which in turn removes the object.

In other cases since list length more than one, it is skipping the 'if' check.


Perform the following local-change:

Change the display property of listtolist control from AccountID to AccountId.
