I migrated to the 20020528 build and can no longer open the launch config dialog. I get this NPE !MESSAGE Unhandled exception caught in event loop. !ENTRY org.eclipse.ui 4 0 May 28, 2002 14:16:04.941 !MESSAGE java.lang.NullPointerException !STACK 0 java.lang.NullPointerException at org.eclipse.pde.internal.ui.launcher.AdvancedLauncherTab.findModel (AdvancedLauncherTab.java:598) at org.eclipse.pde.internal.ui.launcher.AdvancedLauncherTab.validatePlugins (AdvancedLauncherTab.java:586) at org.eclipse.pde.internal.ui.launcher.AdvancedLauncherTab.updateStatus (AdvancedLauncherTab.java:575) at org.eclipse.pde.internal.ui.launcher.AdvancedLauncherTab.initializeFrom (AdvancedLauncherTab.java:415) at org.eclipse.debug.ui.AbstractLaunchConfigurationTabGroup.initializeFrom (AbstractLaunchConfigurationTabGroup.java:78) at org.eclipse.debug.internal.ui.launchConfigurations.LaunchConfigurationDialog.set LaunchConfiguration(LaunchConfigurationDialog.java:1336) at org.eclipse.debug.internal.ui.launchConfigurations.LaunchConfigurationDialog.sel ectionChanged(LaunchConfigurationDialog.java:1265) at org.eclipse.jface.viewers.Viewer.fireSelectionChanged (Viewer.java:147) at org.eclipse.jface.viewers.StructuredViewer.updateSelection (StructuredViewer.java:1154) at org.eclipse.jface.viewers.StructuredViewer.setSelection (StructuredViewer.java:903) at org.eclipse.jface.viewers.Viewer.setSelection(Viewer.java:342) at org.eclipse.debug.internal.ui.launchConfigurations.LaunchConfigurationDialog.doI nitialTreeSelection(LaunchConfigurationDialog.java:453) at org.eclipse.debug.internal.ui.launchConfigurations.LaunchConfigurationDialog.cre ateContents(LaunchConfigurationDialog.java:420) at org.eclipse.jface.window.Window.create(Window.java:278) at org.eclipse.jface.window.Window.open(Window.java:527) at org.eclipse.debug.internal.ui.launchConfigurations.LaunchConfigurationDialog.doL astLaunchedConfig(LaunchConfigurationDialog.java:530) at org.eclipse.debug.internal.ui.launchConfigurations.LaunchConfigurationDialog.ope n(LaunchConfigurationDialog.java:491) at org.eclipse.debug.internal.ui.actions.OpenLaunchConfigurationsAction.run (OpenLaunchConfigurationsAction.java:133) at org.eclipse.jface.action.Action.runWithEvent(Action.java:590) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection (ActionContributionItem.java:407) at org.eclipse.jface.action.ActionContributionItem.handleWidgetEvent (ActionContributionItem.java:361) at org.eclipse.jface.action.ActionContributionItem.access$0 (ActionContributionItem.java:352) at org.eclipse.jface.action.ActionContributionItem$ActionListener.handleEvent (ActionContributionItem.java:47) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java (Compiled Code)) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:825) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:1527) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:1289) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1085) at org.eclipse.ui.internal.Workbench.run(Workbench.java:1068) at org.eclipse.core.internal.boot.InternalBootLoader.run (InternalBootLoader.java:739) at org.eclipse.core.boot.BootLoader.run(BootLoader.java:462) at java.lang.reflect.Method.invoke(Native Method) at org.eclipse.core.launcher.Main.basicRun(Main.java:200) at org.eclipse.core.launcher.Main.run(Main.java:643) at org.eclipse.core.launcher.Main.main(Main.java:476)
I get the same exception whenever I try to create a new runtime workbench configuration.
I had to create a new workspace to solve the problem.
