NPE during "undo" action on view creation ----------------------------------------- Key: TEIIDDES-823 URL: https://issues.jboss.org/browse/TEIIDDES-823 Project: Teiid Designer Issue Type: Bug Components: Editors, Modeling Affects Versions: 7.2 Environment: F14, JBDS-CR2 Reporter: Ramesh Reddy I created a view, which had bad transformation, I edited it, then I hit ctrl-Z couple times, it went back "undo" of the view table itself, and showed the below error. When I selected "redo" view came back fine. It may be hard to reproduce. Also, the refresh action during the "redo" is not complete, it shows un-refreshed screen. org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NullPointerException) at org.eclipse.swt.SWT.error(SWT.java:4083) at org.eclipse.swt.SWT.error(SWT.java:3998) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:137) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:3515) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3164) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2640) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2604) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2438) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:671) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:664) 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(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) 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) Caused by: java.lang.NullPointerException at com.metamatrix.modeler.internal.ui.editors.ModelObjectEditorPanel.deactivate(ModelObjectEditorPanel.java:343) at com.metamatrix.modeler.internal.ui.editors.ModelObjectEditorPanel.close(ModelObjectEditorPanel.java:323) at com.metamatrix.modeler.internal.ui.editors.MultiPageModelEditor.closeObjectEditor(MultiPageModelEditor.java:409) at com.metamatrix.modeler.internal.ui.editors.ModelEditor$8.run(ModelEditor.java:1173) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:134) -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
