Hi,
i have an rcp application written in eclipse 3.6. Now I try to get it running under Eclipse 4.2.
Inside Eclipse it is running just fine, but when i export it, i always get a nullpointer exception.
The exception is thrown by org.eclipse.e4.ui.internal.workbenche.ModelServiceImpl. Is it possible that this Problem is caused by the e4 application model which i didn't use?
Any Help how i could solve this Problem is appreciated.
Thanks,
Thomas

Its creating ModelServiceImpl object with IEclipseContext and then it try to find IEventBroker in this context with is not present so then in next step its throwing java.lang.NullPointerException
public ModelServiceImpl(IEclipseContext appContext) {
if (appContext == null)
return;
IEventBroker eventBroker = appContext.get(IEventBroker.class);
eventBroker.subscribe(UIEvents.UIElement.TOPIC_WIDGET, hostedElementHandler);
}
Are you exporting with all dependency..?
