First, thank you for your reply.
When I stepped through the code, I realized that potential for mishap and in the 'init' I have now only one line 'this.setupenviorment' and this new method has all this code and the debugger clearly shows oApp as on object yet I still have the same error. I am really baffled here specially when this method is done away with and its code is a procedure in the main program, I still get this error.
