NPE when trying to parse existing WizardPages [message #664765]

I'm trying to use Windows Builder to parse some existing hand written Wizard Pages. About 90% of the time I get a NPE when trying to parse the code for the Design page. The other 10% of the time, the page parses, but I get no controls displayed.

Example code can be found at:

http://www.ebayopensource.org/svn/turmeric/soa-platform/trun k/tools/eclipse/plugins/

If you open any of the Wizard pages in the following plugin

org.ebayopensource.turmeric.eclipse.ui

Packages:
org.ebayopensource.turmeric.eclipse.ui
org.ebayopensource.turmeric.eclipse.ui.wizards.pages

I know how to address the anonymous inner class errors, but even then items are not being displayed as I would expect in the designer.

You run code in which expects to see some plugins started.
WindowBuilder does not start OSGi with all plugins - it just create ClassLoader using classpath and runs classes in it. So, for example to open ComplexTypeSCWizardGeneralPage I need to add isDesignTime() check into SOABasePage

		if (!Beans.isDesignTime()) {
		  UIUtil.getHelpSystem().setHelp(container, getHelpContextID());
		}

Okay, that gets me part of the way there. I'll have to go through and check some of the other code to see where I need to do additional design time checks.
