Created attachment 222459 [details] A test project showing the problem When I have a part that doesn't have a method which is annotated with @Focus and I hit return in that part, I get an InjectionException
Teh stack trace is: org.eclipse.e4.core.di.InjectionException: Unable to find matching method to invoke at org.eclipse.e4.core.internal.di.InjectorImpl.invoke(InjectorImpl.java:201) at org.eclipse.e4.core.contexts.ContextInjectionFactory.invoke(ContextInjectionFactory.java:89) at org.eclipse.e4.ui.workbench.renderers.swt.StackRenderer$7.keyTraversed(StackRenderer.java:892) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:265) 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.Widget.sendEvent(Widget.java:1077) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1062) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:774) at org.eclipse.swt.custom.CTabFolder.onTraverse(CTabFolder.java:2061) at org.eclipse.swt.custom.CTabFolder$1.handleEvent(CTabFolder.java:278) 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.Widget.sendEvent(Widget.java:1077) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1062) at org.eclipse.swt.widgets.Control.traverse(Control.java:4050) at org.eclipse.swt.widgets.Control.translateTraversal(Control.java:4032) at org.eclipse.swt.widgets.Display.translateTraversal(Display.java:4794) at org.eclipse.swt.widgets.Display.filterMessage(Display.java:1276) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3754) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine$9.run(PartRenderingEngine.java:1029) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.e4.ui.internal.workbench.swt.PartRenderingEngine.run(PartRenderingEngine.java:923) at org.eclipse.e4.ui.internal.workbench.E4Workbench.createAndRunUI(E4Workbench.java:86) at org.eclipse.e4.ui.internal.workbench.swt.E4Application.start(E4Application.java:150) 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:353) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:180) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:601) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:629) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:584) at org.eclipse.equinox.launcher.Main.run(Main.java:1438) at org.eclipse.equinox.launcher.Main.main(Main.java:1414)
To reproduce: 1) Run the attached project 2) click into the text field inside "Part1" 3) Hit <return> 4) Observe: you get an exception
@Focus currently must be provided, although there's some discussion about making it optional on bug 379024 We should catch the injection exception or use invoke(*) with a default return value and provide a more descriptive log message. PW
I think I fixed this for 4.2.2 *** This bug has been marked as a duplicate of bug 390924 ***
