Bug 296728 [CommonNavigator] Problem with enablement on navigatorContent extension point
If I use the enablement node with the expression "WITH", no variable was found because no real context is given. example : <extension point="org.eclipse.ui.navigator.navigatorContent"> <commonWizard type="new" wizardId="com.mywizard"> <enablement> <with variable="activeWorkbenchWindow.activePerspective"> <equals value="com.myperpective"> </equals> </with> </enablement> </commonWizard> make this error : org.eclipse.core.runtime.CoreException: The variable activeWorkbenchWindow.activePerspective is not defined at org.eclipse.core.internal.expressions.WithExpression.evaluate(WithExpression.java:65) at org.eclipse.core.internal.expressions.CompositeExpression.evaluateAnd(CompositeExpression.java:53) at org.eclipse.core.internal.expressions.EnablementExpression.evaluate(EnablementExpression.java:53) at org.eclipse.ui.internal.navigator.wizards.CommonWizardDescriptor.isEnabledFor(CommonWizardDescriptor.java:145) at org.eclipse.ui.internal.navigator.wizards.CommonWizardDescriptorManager.getEnabledCommonWizardDescriptors(CommonWizardDescriptorManager.java:158) at org.eclipse.ui.navigator.WizardActionGroup.setContext(WizardActionGroup.java:193) at org.eclipse.ui.internal.navigator.resources.actions.NewActionProvider.fillContextMenu(NewActionProvider.java:107) You could do use the currentState of the IEvaluationService.
