Hi Guys,

we have functionality to read data from xml file and display in a list view. Off late this is not working in Dev environment whereas it is working like a charm in QA and Prod. I did Code comparison from the Dev and QA and nothing seems to be missing. I am seeing below stack trace in the Pegarules log file.

Does anybody faced this issue before and resolved it ?
