NullPointerException if I create a VisualClass [message #74804]

Hi,

If I create a VisualClass I always receive a NullPointerException.
in the .log is:

eclipse.buildId=I200409240800

java.vendor=Sun Microsystems Inc.

Note:

I have deinstall the gtk_qt binding from Suse 9.2.
The binding doesn't work on Suse 9.2 and Eclipse 3.1

There has got to be more errors in the .log because this trace has
nothing to do with the VE. It is confusing because this trace indicates
it never even got to the point of bringing up an Eclipse workspace, let
alone start VE.

I also don't know what you mean by deinstalling gtk bindings. VE needs
to have gtk available. Does that mean it is not available?

Also on SUSE, there is a problem in the etc/.hosts file, it has
localhost defined twice, and this screws things up. Go to your
etc/.hosts file and make sure localhost is defined only on the 127.0.0.1
line, and is removed from the :::0 line.

Or is it hosts/.etc (? I forget which is it called).

I'm have clean up my workspace (I create a runtime-workspace for plugin
development) and in this workspace it runs fine.

I can address the wrong setting in my workspace (and I don't want delete them)
There is no more in the .log file!

Any help?

I have deinstalle the gtk-qt-engine which maps the gui from gnome gtk to the KDE
settings/font/gui elements....a gui bridge - I think.

see: https://bugs.eclipse.org/bugs/show_bug.cgi?id=77928

For some reason you are missing the GdkEventMotion, whatever that is.
There is something wrong with your installation. Since it works when you
start from runtime-workspace that means there is something different
between the two eclipse installations, or settings on them. Are you sure
you have Eclipse SWT for GTK installed correctly. It appears to be
missing the Eclipse GTK SWT fragments, or at least the code from them.
