Product Version: NetBeans IDE Dev (Build 200802040003) Java: 1.6.0_03; Java HotSpot(TM) Client VM 1.6.0_03-b05 System: Linux version 2.6.20-16-generic running on i386; UTF-8; en_US (nb) ------------------------------------------------------------------- to reproduce: 1) invoke 'Find Usages' for argv in Welcome project ==> 'Usages' view appears 2) delete Welcome project with the sources 3) click 'Show Logical View' on Usages view ==> java.lang.AssertionError: can't be null declaration at org.netbeans.modules.cnd.completion.csm.CsmDeclarationResolver.findInnerDeclaration(CsmDeclarationResolver.java:128) at org.netbeans.modules.cnd.completion.csm.CsmDeclarationResolver.findInnerFileObject(CsmDeclarationResolver.java:114) at org.netbeans.modules.cnd.completion.csm.CsmOffsetResolver.findObjectWithContext(CsmOffsetResolver.java:101) at org.netbeans.modules.cnd.completion.csm.CsmOffsetResolver.findObject(CsmOffsetResolver.java:90) at org.netbeans.modules.cnd.completion.impl.xref.ReferencesSupport.findOwnerObject(ReferencesSupport.java:122) at org.netbeans.modules.cnd.completion.impl.xref.ReferenceImpl.getOwner(ReferenceImpl.java:75) at org.netbeans.modules.cnd.refactoring.support.CsmRefactoringUtils.getEnclosingElement(CsmRefactoringUtils.java:196) at org.netbeans.modules.cnd.refactoring.ui.tree.RefactoringTreeElement.getCsmParent(RefactoringTreeElement.java:96) at org.netbeans.modules.cnd.refactoring.ui.tree.RefactoringTreeElement.getParent(RefactoringTreeElement.java:70) at org.netbeans.modules.refactoring.spi.impl.RefactoringPanel.createNode(RefactoringPanel.java:434) at org.netbeans.modules.refactoring.spi.impl.RefactoringPanel.access$800(RefactoringPanel.java:86) at org.netbeans.modules.refactoring.spi.impl.RefactoringPanel$5.run(RefactoringPanel.java:684) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:561) [catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:986)
fixed. check valid state of reference log: http://hg.netbeans.org/main?cmd=changeset;node=8a9140e6af08
to reproduce: 1) Open disk.cpp in Quote project 2) invoke "Find Usages" for GetType() 66:23 3) click "Show Logical View" on Usage view and double-click on leaf-node 4) switch back to Physical View 5) delete Quote project 6) click 'Show Logical View' on Usage view ==> java.lang.AssertionError: can't be null declaration at org.netbeans.modules.cnd.refactoring.support.CsmRefactoringUtils.findInnerDeclaration(CsmRefactoringUtils.java:400) at org.netbeans.modules.cnd.refactoring.support.CsmRefactoringUtils.findInnerFileObject(CsmRefactoringUtils.java:388) at org.netbeans.modules.cnd.refactoring.support.CsmRefactoringUtils.findInnerFileObject(CsmRefactoringUtils.java:437) at org.netbeans.modules.cnd.refactoring.support.CsmRefactoringUtils.getEnclosingElement(CsmRefactoringUtils.java:199) at org.netbeans.modules.cnd.refactoring.ui.tree.RefactoringTreeElement.getCsmParent(RefactoringTreeElement.java:97) at org.netbeans.modules.cnd.refactoring.ui.tree.RefactoringTreeElement.getParent(RefactoringTreeElement.java:71) at org.netbeans.modules.refactoring.spi.impl.RefactoringPanel.createNode(RefactoringPanel.java:434) at org.netbeans.modules.refactoring.spi.impl.RefactoringPanel.access$800(RefactoringPanel.java:86) at org.netbeans.modules.refactoring.spi.impl.RefactoringPanel$5.run(RefactoringPanel.java:684) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:561) [catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:986) I think the best solution is to clear (and close) Usage view if the project have been deleted.
fixed: - use container for removed objects log: http://hg.netbeans.org/main?cmd=changeset;node=0cf9c565b6bb http://hg.netbeans.org/main?cmd=changeset;node=b8487de063f3 P.S. we can not close once displayed tabs, this is request to NB
