Error message when looping a page group

SA-45628

Summary



Error in the Tracer when looping a page group in an activity.


Error Messages



Exception message: The property PageName.PageGroupName(Subscript) was of mode String while com.pega.pegarules.data.internal.clipboard.ClipboardPropertyImpl.getPageValue() was expecting Page mode. Details: (none)


Steps to Reproduce



Unknown


Root Cause



An issue in the custom application code or rules.

The page group was populated from the contents of a report definition and one page did not have pxObjClass and pxSubscript. Hence, the exception occurred when this page was opened.


Resolution



Here’s the explanation for the reported behavior:

As one page in the page group did not have the pxObjClass and pxSubscript, the mode of the page was not identified correctly as a page. Custom code populated the page group. This must be reviewed and revised to correctly update the page group.
