Hi!

Our application crashes when CloseWithReturn is called in the window open() event handler. The error occurs when returning early from the Open() handler when incorrect parameters are passed.

My code:

...

integer retval = CloseWithReturn(this, 0)

---

retval is -1, indicating some error.  The window is not closed so the code execution continues. Apparently the window object is destroyed(partly?) and inevitably the application crashes. I suspect maybe other messages are trying to reach the Open() event for handling but haven't found out how to solve that eventuality

 

- Is it legal (or recommended) to do CloseWithReturn() in Open()

- What would be a better graceful termination of the window in an error situation? 

 

Cheers

Haakon
