When moving inside a package a set of classes linked together through associations and generalizations, I have the following error: !ENTRY org.eclipse.core.commands 4 2 2010-08-17 15:06:10.218 !MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.core.commands". !STACK 0 java.lang.NullPointerException at org.eclipse.papyrus.diagram.common.layout.SameAlignment.getEditPartRepresentationFor(SameAlignment.java:200) at org.eclipse.papyrus.diagram.common.helper.AlignmentLinkHelper.organizeSelection(AlignmentLinkHelper.java:145) at org.eclipse.papyrus.diagram.common.helper.AlignmentLinkHelper.createCommand(AlignmentLinkHelper.java:73) at org.eclipse.papyrus.diagram.common.actions.CustomAlignAction.getCommand(CustomAlignAction.java:210) at org.eclipse.gmf.runtime.diagram.ui.actions.DiagramAction.getCommand(DiagramAction.java:161) at org.eclipse.gmf.runtime.diagram.ui.actions.DiagramAction.calculateEnabled(DiagramAction.java:124) at org.eclipse.gmf.runtime.diagram.ui.actions.DiagramAction.refresh(DiagramAction.java:114) at org.eclipse.gmf.runtime.common.ui.action.AbstractActionHandler.historyNotification(AbstractActionHandler.java:602) at org.eclipse.core.commands.operations.DefaultOperationHistory$2.run(DefaultOperationHistory.java:939) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.core.commands.operations.DefaultOperationHistory.notifyListeners(DefaultOperationHistory.java:928) at org.eclipse.core.commands.operations.DefaultOperationHistory.notifyDone(DefaultOperationHistory.java:1002) at org.eclipse.core.commands.operations.DefaultOperationHistory.execute(DefaultOperationHistory.java:527) at org.eclipse.gmf.runtime.diagram.ui.parts.DiagramCommandStack.execute(DiagramCommandStack.java:206) at org.eclipse.gmf.runtime.diagram.ui.parts.DiagramCommandStack.execute(DiagramCommandStack.java:169) at org.eclipse.gmf.runtime.diagram.ui.parts.DiagramCommandStack.execute(DiagramCommandStack.java:156) at org.eclipse.gef.tools.AbstractTool.executeCommand(AbstractTool.java:426) at org.eclipse.gef.tools.AbstractTool.executeCurrentCommand(AbstractTool.java:443) at org.eclipse.gmf.runtime.diagram.ui.tools.DragEditPartsTrackerEx.executeCurrentCommand(DragEditPartsTrackerEx.java:151) at org.eclipse.gef.tools.DragEditPartsTracker.performDrag(DragEditPartsTracker.java:491) at org.eclipse.gef.tools.DragEditPartsTracker.handleButtonUp(DragEditPartsTracker.java:346) at org.eclipse.gef.tools.AbstractTool.mouseUp(AbstractTool.java:1206) at org.eclipse.gef.tools.SelectionTool.mouseUp(SelectionTool.java:572) at org.eclipse.gef.EditDomain.mouseUp(EditDomain.java:301) at org.eclipse.gef.ui.parts.DomainEventDispatcher.dispatchMouseReleased(DomainEventDispatcher.java:380) at org.eclipse.draw2d.LightweightSystem$EventHandler.mouseUp(LightweightSystem.java:548) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:213) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1053) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:4066) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3657) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2629) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2593) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2427) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:670) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:663) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:369) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:619) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:574) at org.eclipse.equinox.launcher.Main.run(Main.java:1407) at org.eclipse.equinox.launcher.Main.main(Main.java:1383)
Created attachment 176797 [details] mylyn/context/zip impacted classes
the list contained null value, a test has been added. Can you test before close the bug.
I have made a test, there is no more errors. But I can not see all the classes inside the package. Even if I enlarge the package, I can't see correctly all the classes and associations.
I works fine now, I have used the "arrange all" button, and I can see all the classes inside the package.
I close the bug
