[news.eclipse.rt.riena] Re: where to do the remote service call

[Thorsten Schenkel <thorsten.schenkel@xxxxxxxxxxxx>]

Hi Sjoerd,

you can add to every node of the navigation a listener 
(NavigationNodeListener).
So you will be informed after every change of status of the navigation node.

example:


@Override
public void setNavigationNode(ISubModuleNode navigationNode) {

	super.setNavigationNode(navigationNode);

	getNavigationNode().addListener(new SubModuleNodeListener() {
		@Override
		public void afterDeactivated(ISubModuleNode source) {
			super.afterDeactivated(source);
			getStatusLine().clear();
		}
	});
}

greetings

Thorsten
