Yea, its been a while and I started thinking about just having something like what you mentioned, a NavigationPresentor. Just really wanted something outside of my other presentors that could have access to the navigator to push the view.

thanks.

You could do it with a presenter. Both ways can work, but if I were you, I’d look at the pros and cons of both patterns. Like I said in the article, I used a Mediator pattern for a very specific reason, but both can the do the same work in essence. In your case, I would image you’d want a ‘NavigationPresenter’ of sorts that can listen for those async events and then decide what to do from there. I don’t know exactly what your requirements are, but I’m sure that there is a reasonable way of doing this. You could have some sort of config that says “if event X is dispatched, show view Y”.

Although I understand what you are saying about components being tied to the framework by depending on the context to inject something. I for one usually make it a point to only have my framework actors be it mediator or pm limited to my project screens/views (the containers). These will then hold and pass through any data to any reusable components I would have inside them. I would think in most cases the containers would be specific the one project but I guess every situation is different as well. Thats the approach I usually take.

On another note. This looks like a good solution to my mobile application issue. basically I feel someone what uncomfortable with one View telling the navigator what the next View to load is. especially after an async command. with this i can just have a mediator for the view navigator take care of that for me. I couldn’t see how a presentation model would handle that while needing a reference to the actual navigator.

What do you think?

Hey Tihomir,

I would be glad to help you. Could you pastebin what you’re trying to do (the mediator, the view and the context) and I can suggest how to fix it.

Hi, I’m having some problems using this extension. initView() method in the mediator is triggered different number of times in different occasions, so it’s sometimes triggered two times, sometimes one (as it should I believe) and sometimes it’s not triggered at all. Did anybody else experienced this problem?
Btw, very good extension.
Cheers
