Hello,

I have a module which uses GUIKit to build some user interface in
Mathematica.

It works OK from Mathematica frontend but it does not work in batch
mode:

"f:/program files/wolfram research/mathematica/7.0/math.exe" -initfile
".../path/gui-module.m" -noprompt

Get out the exception:

GUIRun::err: The following GUIKit runtime error
occurred :java.lang.NullPointerException.

GUIRunModal::nvalid: The GUI definition contains invalid content.

What may be the reason?

Regards,

-Andrey
