Assertion error trying to Delete a file --------------------------------------- Key: TEIIDDES-2471 URL: https://issues.jboss.org/browse/TEIIDDES-2471 Project: Teiid Designer Issue Type: Bug Components: Modeling Affects Versions: 9.0 Reporter: Barry LaFond Assignee: Paul Richardson Fix For: 9.2 When deleting a VDB in a model project, it'll fail if you click *Preview*, then *Back*, then *OK* Stack trace is below and it appears that by Previewing the a refactor action (Delete in this case) and clicking *Back* does not clear the original *change*, so clicking *OK* ends up trying to apply duplicate changes. I tested the Preview/Back a couple of times and verified it's adding a duplicate change each time. {code} org.eclipse.core.runtime.CoreException: assertion failed: DeleteResourcesRefactoring class is adding a at org.teiid.designer.ui.refactor.delete.DeleteResourcesRefactoring.createChange(DeleteResourcesRefactoring.java:232) at org.eclipse.ltk.core.refactoring.CreateChangeOperation.run(CreateChangeOperation.java:124) at org.eclipse.ltk.core.refactoring.PerformChangeOperation.run(PerformChangeOperation.java:209) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:2313) at org.eclipse.ltk.internal.ui.refactoring.WorkbenchRunnableAdapter.run(WorkbenchRunnableAdapter.java:87) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:122) !SUBENTRY 1 org.teiid.designer.ui.refactor.delete 4 0 2015-04-06 08:26:20.007 !MESSAGE assertion failed: {code}
