Error Messages


Steps to Reproduce

Open any existing Work-Item in IE, add note "İstanbul" submit.

Close and Open the notes tab to view the previously added notes. Add another note.
Now, open the same Work-Item in Google Chrome and access the notes tab. You will not be able to open and view the notes.

Root Cause

JSON Parse exception was only observed in Chrome and not in Microsoft IE9 and Mozilla FireFox. The root cause of this problem is due to an issue in Google Chrome while convert Latin capital "İ" to lowercase in the Pega JavaScript function toLowerCase(). 


was provided to handle the issue in PRPC by using toUpperCase function (instead of toLowerCase) and get the start and end Div tag length in the above JavaScript function (until Chrome has fixed the toLowerCase JS function for Latin capital letter "İ").
