I am trying to add a banner to the top tool bar in an e3 rcp application running in Luna eclipse 4.4.
The type BannerImpl is an extension of ToolControlImpl that simply makes its constructor visible by calling super(); in its constructor.
plugin/BannerPart is a composite that adds the banner.
ApplicationImpl app = (ApplicationImpl) PlatformUI.getWorkbench().getService(MApplication.class);
List<MWindow> t = app.getChildren();
TrimmedWindowImpl trimmed = ((TrimmedWindowImpl) t.get(0));
List<MTrimBar> trimbars = trimmed.getTrimBars();
BannerImpl p = new BannerImpl();
p.setContributionURI("bundleclass://plugin/BannerPart");
trimbars.get(0).getChildren().add(p)
The banner is successfully added, but now when ever the function
WorkbenchPage.closePerspective(id, Boolean, Boolean) is called the following exception is thrown
!MESSAGE Exception while dispatching event org.osgi.service.event.Event [topic=org/eclipse/e4/ui/model/ui/ElementContainer/children/REMOVE] to handler org.eclipse.e4.ui.internal.di.UIEventObjectSupplier$UIEventHandler@5927f904

What is the reason that this would be occurring? I am simply adding to a trimBar when the application starts so I am very confused as to why this would have any interaction with the closePerspective function.
