While working on a Ajax ( C & S ) script,
I am getting following error.

Warning -26000: Setting window.opener to an unsupported type (2) [MsgId: MWAR-26000]
Warning -26499: Internal Error – Unsupported JavaScript property (tiny ID=-33) for object topwindow in xfbLrwJswSetDomProperty for ptUserObj=020EA818 [MsgId: MWAR-26499]
web_button(“INPUT_4”) highest severity level was “warning” [MsgId: MMSG-26391]
