Hi,
I would like to register PerspectiveListener an open an editor if a special
perspective becomes activated.
Normally I do this in my Activator.start() method. But I get the
"IllegalStateException" because no context ist available. I also tried it
with UICallBack.runNonUIThreadWithFakeContext() but since this method also
needs a Display I get the same Exception.
Am I doing something wrong? Is there a better place to register my Listener
at where it works better?
Regards,
Markus

Hi again,
you could even use an IStartup implementation contributed by an
extension to org.eclipse.ui.startup.
