See a different exception in the WTP build: S-2.0M5-200702220244 . However, I am now able to use the property editor. I am assuming this exception will go away once we pick the Eclipse M5a build. eclipse.buildId=I20070209-1006 Unhandled event loop exception java.lang.IllegalArgumentException: Argument cannot be null at org.eclipse.swt.SWT.error(SWT.java:3462) at org.eclipse.swt.SWT.error(SWT.java:3401) at org.eclipse.swt.SWT.error(SWT.java:3372) at org.eclipse.swt.graphics.GC.setBackground(GC.java:3598) at org.eclipse.ui.internal.views.properties.tabbed.view.TabbedPropertyTitle.drawTitleBackground(TabbedPropertyTitle.java:144) at org.eclipse.ui.internal.views.properties.tabbed.view.TabbedPropertyTitle$1.paintControl(TabbedPropertyTitle.java:81) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:204) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:66) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:938) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:962) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:947) at org.eclipse.swt.widgets.Composite.WM_PAINT(Composite.java:1178) at org.eclipse.swt.widgets.Control.windowProc(Control.java:3527) at org.eclipse.swt.widgets.Display.windowProc(Display.java:4172) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:2200) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3102) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2264) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2228) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2103) at org.eclipse.ui.internal.Workbench$4.run(Workbench.java:457) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:289) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:452) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:101) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:146) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:106) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:76) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:354) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:169) 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:585) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:476) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:416) at org.eclipse.equinox.launcher.Main.run(Main.java:1124)
I will add this to 174442
Closing as part of mass query to clean up old resolved bugs in untargetted milestones.
