[jboss-jira] [JBoss JIRA] Updated: (GPD-128) ClassCastException in XmlAdapterFactory.getConfigurationElementByXmlElementName(String)

[ http://jira.jboss.com/jira/browse/GPD-128?page=all ] John Ruud updated GPD-128: -------------------------- Koen, My stack trace is included (below). While my own classes are involved in this case, it may hopfully be clear by looking at line 43 of XmlAdapterRegistry why the exception occurs (a TreeSet is added to xmlElementMap, but in line 52 this Set is then attempted casted to an IConfigurationElement) John !ENTRY org.eclipse.ui 4 4 2007-08-05 14:16:41.843 !MESSAGE Unhandled event loop exception !ENTRY org.eclipse.ui 4 0 2007-08-05 14:16:41.890 !MESSAGE java.util.TreeSet cannot be cast to org.eclipse.core.runtime.IConfigurationElement !STACK 0 java.lang.ClassCastException: java.util.TreeSet cannot be cast to org.eclipse.core.runtime.IConfigurationElement at org.jbpm.gd.common.registry.XmlAdapterRegistry.getConfigurationElementByXmlElementName(XmlAdapterRegistry.java:52) at com.thrasys.gd.xpdl.model.ModelFactory.getSemanticElementId(ModelFactory.java:53) at com.thrasys.gd.xpdl.model.ModelFactory.createByElementId(ModelFactory.java:60) at com.thrasys.gd.xpdl.model.ModelFactory.addXNetXml(ModelFactory.java:92) at com.thrasys.gd.xpdl.model.Node.initializeNew(Node.java:9) at org.jbpm.gd.common.editor.CreationFactory.getNewObject(CreationFactory.java:35) at org.eclipse.gef.requests.CreateRequest.getNewObject(CreateRequest.java:73) at org.jbpm.gd.common.policy.XYLayoutEditPolicy.initCreateCommand(XYLayoutEditPolicy.java:58) at org.jbpm.gd.common.policy.XYLayoutEditPolicy.getCreateCommand(XYLayoutEditPolicy.java:42) at org.eclipse.gef.editpolicies.LayoutEditPolicy.getCommand(LayoutEditPolicy.java:199) at org.eclipse.gef.editpolicies.ConstrainedLayoutEditPolicy.getCommand(ConstrainedLayoutEditPolicy.java:154) at org.eclipse.gef.editparts.AbstractEditPart.getCommand(AbstractEditPart.java:473) at org.eclipse.gef.tools.TargetingTool.getCommand(TargetingTool.java:122) at org.eclipse.gef.tools.CreationTool.handleMove(CreationTool.java:239) at org.eclipse.gef.tools.AbstractTool.mouseMove(AbstractTool.java:1038) at org.eclipse.gef.EditDomain.mouseMove(EditDomain.java:248) at org.eclipse.gef.ui.parts.DomainEventDispatcher.dispatchMouseMoved(DomainEventDispatcher.java:359) at org.eclipse.draw2d.LightweightSystem$EventHandler.mouseMove(LightweightSystem.java:533) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:145) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:66) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:928) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3348) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2968) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1930) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1894) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:422) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:95) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:78) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:92) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:68) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:400) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:177) 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.core.launcher.Main.invokeFramework(Main.java:336) at org.eclipse.core.launcher.Main.basicRun(Main.java:280) at org.eclipse.core.launcher.Main.run(Main.java:977) at org.eclipse.core.launcher.Main.main(Main.java:952) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
