Hi,
I am making use of SWT_AWT bridge for bring my Swing application into
Eclipse/SWT (I cannot move higher from Eclipse/SWT 3.2 and hence I am using
SWT_AWT and not Albireo). While doing so, I referred to the article
http://www.eclipse.org/articles/article.php?file=Article-Swi ng-SWT-Integration/index.html
by Gordon Hirsch and recently made use of his Example code given there. As
per this, all the necessary workarounds to make SWT_AWT work for you are
applied to a subclass object of Composite (EmbeddedSwingComposite in his
code). As per his recommendation I subclassed this and then used it in my
code. However, I am encountering NPE on the EventThread and while trying to
find solutions for the same I came across this:
http://dev.eclipse.org/mhonarc/lists/platform-swt-dev/msg046 14.html which
suggests NOT to subclass Composite.
Is this a known issue with SWT_AWT and is there any workaround for the same?
Any help/direction would be really useful!
Thanks,
Rahul

If you are using EmbeddedSwingComposite from the example code, the AWT
frame is embedded directly into the SWT.EMBEDDED composite, so the email
you refer to should not apply.
Byeond that, a stack trace might help shed light on the problem.
