If a MasterDetailsComposite gets created and no IMasterDetailsComposite gets supplied via the setDelegate-Method a NullPointerException is thrown, when the User selects a row in the Table: java.lang.NullPointerException at org.eclipse.riena.internal.ui.ridgets.swt.MasterDetailsRidget.updateDetails(MasterDetailsRidget.java:341) at org.eclipse.riena.internal.ui.ridgets.swt.MasterDetailsRidget.handleSelectionChange(MasterDetailsRidget.java:415) at org.eclipse.riena.internal.ui.ridgets.swt.MasterDetailsRidget.access$3(MasterDetailsRidget.java:411) at org.eclipse.riena.internal.ui.ridgets.swt.MasterDetailsRidget$DirtyDetailsChecker.widgetSelected(MasterDetailsRidget.java:447) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:228) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1003) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3880) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3473) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2405) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2369) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2221) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:500) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:493) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.riena.navigation.ui.swt.application.SwtApplication.createView(SwtApplication.java:64) at org.eclipse.riena.navigation.ui.application.AbstractApplication.start(AbstractApplication.java:63) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:194) 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:368) 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:585) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:559) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:514) at org.eclipse.equinox.launcher.Main.run(Main.java:1311) at org.eclipse.equinox.launcher.Main.main(Main.java:1287) Instead it would be much more userfriendly, if a IllegalStateException would be thrown as soon as possible so the Developer gets notified that he did not implement the API correctly.
+1 I agree
@Steffen: Now that the other MasterDetails patch is in - would you like to address this as well?
Created attachment 147677 [details] Patch Throws a IllegalStateException in updateFromModel if no delegate was supplied.
Thanks, resolved.
