I installed a lot of Indigo plug-ins and was unable to open the 'Progress' view. From the trace I guess it is dying in MoDisco's code though that's not to necessarily say they are at fault here. java.lang.NullPointerException at

MoDisco's ContributionItemForMoDiscoMenu's fill(Menu, int) implementation arbitrarily retrieves the menu's shell, calls getData() on it, and then downcasts the result to IWorkbenchWindow. This is not documented API. Based on your code, it seems you just want a selection listener, you can retrieve this from a service locator. What you should do instead is the following: public class ContributionItemForMoDiscoMenu extends ContributionItem implements IWorkbenchContribution { private ISelectionService selectionService; public void initialize(IServiceLocator serviceLocator) { selectionService = (ISelectionService) serviceLocator.getService(ISelectionService.class); } }
Thank you Remy. Fixed in revision 4364 by using the IServiceLocator, both in org.eclipse.modisco.infra.discovery.ui and the deprecated org.eclipse.gmt.modisco.infra.discoverymanager.
Bug solved.
