Build Identifier: Build id: 20110916-0149, Papyrus 0.8.1.v201109301802 Trying to create nested StructuredActivityNodes (SequenceNode, ConditionalNode, LoopNode), (depth > 3) I obtained the following NullPointerException (and the nested node is not created) : java.lang.NullPointerException at org.eclipse.gmf.runtime.diagram.ui.editpolicies.XYLayoutEditPolicy.getConstraintFor(XYLayoutEditPolicy.java:229) at org.eclipse.gef.editpolicies.ConstrainedLayoutEditPolicy.getAddCommand(ConstrainedLayoutEditPolicy.java:184) at org.eclipse.gef.editpolicies.LayoutEditPolicy.getCommand(LayoutEditPolicy.java:216) at org.eclipse.gef.editpolicies.ConstrainedLayoutEditPolicy.getCommand(ConstrainedLayoutEditPolicy.java:214) at org.eclipse.gmf.runtime.diagram.ui.editpolicies.XYLayoutEditPolicy.getCommand(XYLayoutEditPolicy.java:325) at org.eclipse.papyrus.diagram.common.groups.edit.policies.XYLayoutEditGroupPolicy.getCommand(XYLayoutEditGroupPolicy.java:117) at org.eclipse.gef.editparts.AbstractEditPart.getCommand(AbstractEditPart.java:502) at org.eclipse.gmf.runtime.diagram.ui.editparts.GraphicalEditPart.access$1(GraphicalEditPart.java:1) at org.eclipse.gmf.runtime.diagram.ui.editparts.GraphicalEditPart$1.run(GraphicalEditPart.java:482) at org.eclipse.emf.transaction.impl.TransactionalEditingDomainImpl.runExclusive(TransactionalEditingDomainImpl.java:328) at org.eclipse.gmf.runtime.diagram.ui.editparts.GraphicalEditPart.getCommand(GraphicalEditPart.java:477) at org.eclipse.gef.tools.DragEditPartsTracker.getCommand(DragEditPartsTracker.java:281) at org.eclipse.gef.tools.DragEditPartsTracker.handleDragInProgress(DragEditPartsTracker.java:370) at org.eclipse.gef.tools.AbstractTool.mouseDrag(AbstractTool.java:1114) at org.eclipse.gef.tools.SelectionTool.mouseDrag(SelectionTool.java:538) at org.eclipse.gef.EditDomain.mouseDrag(EditDomain.java:259) at org.eclipse.gef.ui.parts.DomainEventDispatcher.dispatchMouseMoved(DomainEventDispatcher.java:363) at org.eclipse.draw2d.LightweightSystem$EventHandler.mouseMove(LightweightSystem.java:543) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:211) 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:4165) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3754) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2696) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2660) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2494) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:674) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:667) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:123) 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:344) 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:622) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:577) at org.eclipse.equinox.launcher.Main.run(Main.java:1410) Reproducible: Always Steps to Reproduce: 1. In an activity diagram, create a SequenceNode N1 2. Create a LoopNode N2 in N1 3. Create a SequenceNode N3 in N2 : it fails.
In the current version (0.10.0), nested Structured Activity Nodes cannot be created at all (Without any exception). The task has been renamed accordingly.
Works in the current version
