Unfortunately I can't see a way how to pass an optional parameter to the router such as appDetail('appId', 'activity') [1].

Since parameters are mandatory, we would need to pass the information about activity outside the navigation handling when link is clicked (such as pass it to auxiliary controller) - that doesn't seem systematic.

I believe we could fix this with upgrade to latest router but it is too late in beta1 to do that. Let's try to get this in early beta2 development.
