I went down the road of the PlaceHyperlink [trying to create as extension of Hyperlink with a method setDestination(Place)]. My intention was that PlaceHyperlink could be used in UIBinder, and my presenters wouldn't all need to pass through a PlaceHistoryMapper.
I have GIN set up, so I'm trying to inject my PlaceHistoryMapper into my PlaceHyperlink (as a field injection - to avoid the missing no-arg constructor problem), but no dice. That PHM is always null (although it works fine in other places when constructor-injected).

I don't totally understand why this doesn't work. Any thoughts how to implement a PlaceHyperlink with UIBinder and GIN?

If you just have a shallow Place object (say it only knows an ID) and always fetch the data you need, that means more calls.If you let the Place object contain a lot more data, you still have to code for when it doesn't (eg., when the user navigates directly to a URL or does a right-click -> Open in new tab...).I was just curious if there's a preferred pattern here.IMO you should prefer the preventDefault+PlaceController#goTo way (and don't forget to code the "fallback" in the target PlaceChangeEvent.Handler and/or Activities!), as it's really small overhead for the developer (you could even make a PlaceHyperlink(PlaceHistoryMapper, Place) to avoid repeating the same things again and again) and a real win for the user.--To view this discussion on the web visit https://groups.google.com/d/msg/google-web-toolkit/-/a-fAcWjwkGYJ.
