Any ideas? Maybe something changed in the way the navigation model has to be constructed? This is done in Application#createModel in the o.e.r.sample.app.client.mail package.
Hi Riena colleagues, any input here? If you are familiar with the navigation id things, please leave a comment :-).
Hi Elias, can you tell me which object is null? I'm not at my riena desktop right now... I'll have a look ...

Any ideas what those id's are and where they should be defined ? I don't understand the Navigation-Model at that detail level... The example used to work, so I think it is caused by changes / new requerements regarding the id's. Maybe the place where we construct the navigation for the example ( Application#createModel ) has to be updated ?
I think you could fix it just by calling the SubApplicationNode-Constructor public SubApplicationNode(final NavigationNodeId nodeId, final String label) in org.eclipse.riena.sample.app.client.mail.Application inside createModel(). But I think this is just a workaround as it is absolutly valid to call the constructor without the NavigationNodeId. I'll have a look.
