Bug 174806 [Import/Export] setupSelectionsBasedOnSelectedTypes() casts to IResource
Reported: 2007-02-20 11:50:40 | Status: verified fixed

Build ID: M20060921-0945 Steps To Reproduce: 1. Build a plug-in extending org.eclipse.ui.exportWizards, using org.eclipse.ui.dialogs.WizardExportResourcesPage 2. Select a Java project 3. Select export and the export provided by the new plug-in -> Class cast exception occures This is, because setupSelectionsBasedOnSelectedTypes() casts to IResource, but this interface is not implemented by JavaProject (not implemented by other project classes either).
