Comment 2 Tomas Zezula 2010-03-15 14:14:02 UTC 
The WizardDescriptor.Panel.getComponent() javadoc says that it can be called by any thread but it's seems wrong as according to http://performance.netbeans.org/howto/dialogs/wizard-panels.html the Panel cannot construct UI components in the constructor and it has to return component from getComponent() where it cannot be created as it is not in the EDT. Only way how to do it is to use SwingUtilities.invokeAndWait which may cause dead lock.
So better way is to fix it in the TemplateWizard.updateState, which should do the same as a WizardDescriptor.updateState (reschedule to EDT when needed).
Comment 3 Stanislav Aubrecht 2012-09-11 08:53:10 UTC 
This should be fixed in #217446, please reopen if still reproducible.
