NullPointerException in isValidThread [message #50702]

Hi,
since RC1 we have some strange NullPointerExceptions each time we're
trying to call a method from super, where the method checkWidget is called.
Does anyone knows about this issue with the change to RC1?
I'll try to gather more information about it.
Thanks

Oliver

Hi,

sorry for the delay we all had many things to do before the 1.0 release.
It would be great if you can provide a stacktrace and maybe a snippet to
reproduce the problem. It's hard for us to reproduce such things without
further informations.

Hi Benny,
I've already found the solution to the problem.
I've realized that I have overridden the getDisplay method which
returned null in my Custom widget. In earlier version of RAP that was
never a problem as this function was never called from isValidThread or
checkWidget. But now it was. So I removed the method getDisplay from my
custom widget so that Widget.getDisplay() will be called.
In the end it was my own stupidity not take care of that ;-)
Anyway thanks for the answer.
Regards

Oliver
