Prism Event Aggregation - subscriber not triggered

Question

I\'m working on implementing an event aggregation with Prism. I have a few modules, and I want each of them to subscribe to events that tells them when they are requested. I sta

So, I just got a theory, but no time to test it right now.. Will do tomorrow.

Question: Will adding modules to the ModuleCatalogue keep them alive? I assumed it would. Hence - the MyModule should stay alive - and then will be triggered when the event is published.

protected override IModuleCatalog GetModuleCatalog()
{
    var catalog = new ModuleCatalog();
    catalog.AddModule(typeof(MyModule));
    return catalog;
}

However, if this doesn't keep the module alive it is obvious that it will have a hard time respond to the event. The module-object dies, but it doesn't unsubscribe - hence I'll see the subscriber in the EventAggregator list, but the subscriber isn't around anymore. Also; I mentioned that I it does in fact work occasionally - which would be the case if the garbage collector didn't have time to take out the trash before the event is triggered.

Does this sound like the case? If so - I haven't thought of a solution yet so you're welcome to suggest one in a different reply-thread..

So; what is the ModuleCataloge anyway? Just a list kept for Initialization and then thrown away?
