Description

Hello it is quite difficult to debug when errors are thrown in the second rendering phase.

I had the problem with WTextEdit. Apparently setText() has a preconditions: text must not be null. This is however not document and not checked. Could you add the checking on set?

Best regards,
Thim.

We will check for each String argument that is passed to the public API that it is not null.
