Build Identifier: CVS Head as of 2010-12-23 During a query, the dirtyIndex field in DirtyResourceFactory turns out to be null and gives a NullPointerException in EmfHelper.getReferringElementsWithTypeAndInScope(...). It is not clear to me which initialization I'm probably missing.

The query I'm firing is this: select me from [http://www.eclipse.org/emf/2002/Ecore#//EClassifier] as me,[http://www.furcas.org#//TCS/ContextTemplate] as ct,[http://www.furcas.org#//TCS/ContextTags] as tags,[http://www.furcas.org#//TCS/ConcreteSyntax] as cs in elements {[http://www.furcas.org/transientParsingResource_eH7qUA55EeCSRoxfOLGwIQ#/1]} where ct.concreteSyntax=cs where ct.metaReference=me where ct.contextTags=tags where ct.isContext=true where tags.tags='bibtexfile' I've checked the broken scenario into a github repository git://github.com/FURCAS-dev/FURCAS.git as branch broken_query2_test. Clone the branch. Open an Eclipse instance with the git repository as your workspace. Hit the update site at http://furcas-dev.github.com/FURCAS/update-site and from the "FURCAS Textual Modelling" group install feature "Workspace Setup". Restart Eclipse. You should see a little white icon in your toolbar tooltipped "Initialize Furcas Workspace". Run it. Then you should find a launch configuration ReferenceResolvingTests. Run it. The setup of TestPropertyInitReEvaluationWithContextInForeachTriggeredTemplate should reproduce the problem.
Hi Axel, DirtyResourceFactory has been introduced to keep track of the dirty index. Could you please check this link https://bugs.eclipse.org/bugs/show_bug.cgi?id=324176 And also the TestQueryBugs.java which contains an example of how the DirtyResourceFactory could be setup. cheers, Saurav
It seems the DirtyResourceFactory instance could use some initialization. A tiny ugly patch that fixes it quick/dirty for us is this: diff --git a/EMF/query2/org.eclipse.emf.query2/plugins/org.eclipse.emf.query2.core/src/org/eclipse/emf/query2/internal/shared/EmfHelper.java b/EMF/query2/org.eclipse.emf.query2/plugins/org.eclipse.emf.query2.core/src/org/eclipse/emf/query2/ internal/shared/EmfHelper.java index 26b483a..e573fcb 100644 --- a/EMF/query2/org.eclipse.emf.query2/plugins/org.eclipse.emf.query2.core/src/org/eclipse/emf/query2/internal/shared/EmfHelper.java +++ b/EMF/query2/org.eclipse.emf.query2/plugins/org.eclipse.emf.query2.core/src/org/eclipse/emf/query2/internal/shared/EmfHelper.java @@ -239,7 +239,7 @@ public class EmfHelper { private Index getBackwardNavIndex() { if (useDirty) { //The dirty index is maintained by the DirtyResourceFactory - return DirtyResourceFactory.getIndex(); + return DirtyResourceFactory.getInstance().getIndex(); } else { return this.index; }
Provided the NPE check in the Query core code where it accesses the DirtyResourceFactory. Hence closing the bug
