Does the MVP framework included in GWT 2.1 make other GWT MVP frameworks redundant?

Question

GWT 2.1 includes an MVP framework which includes an implementation of the PlaceService outlined by Google's Ray Ryan at Google I/O 2009.

That talk inspired some MVP frameworks like

• GWT-presenter
• GWT-Platform (GWTP)
• MVP4G

Does GWT 2.1 make using these additional frameworks redundant?

Answer 1

Yes, there is overlap, and perhaps those other frameworks will become unnecessary down the road. But, from a practical perspective, to date there don't seem to be too many solid examples that use the new 2.1 features. On my current project we spent a little time evaluating the 2.1 MVP constructs and settled on using the GWT-presenter framework because we were able to make progress a lot faster using examples such as the Hupa mail client.

Unfortunately, all of these frameworks seem to lack solid documentation. They all seem to give you a trivial Hello World example, without showing you the essential details necessary to do anything more than a trivial example. The only way to learn is to dig through code.

We used GWT Presenter 1.0 but are considering removing in a redesign. Still hoping more GWT MVP practitioners will answer/vote to get a more cross section of opinion. – Sunnisunnite

I see that GWTP creator Philippe Beaudoin said on Jul 29 2010 that "the feature gap between GWTP and GWT's 2.1 MVP classes is a bit too large" and GWTP will be maintained and upgraded for now (gwtsushi.info/2010/06/…). I guess this confirms that at the moment the 3rd party MVP frameworks still have their place. – Sunnisunnite

Additionally, Philippe Beaudoin said in Nov 2010 - "2.1 MVP is closer to the metal and will need you to write more code & 2.1 MVP are still meant to sit behind a 3rd party tool" - code.google.com/p/gwt-platform/wiki/ComparisonWithGwtMVP – Sunnisunnite

Regarding example, gwt-platform tries really hard to provide many examples of the different functionalities, together with a larger integrated example in the form of PuzzleBazar. Moreover, the community there is large and helpful. I think the same hold true for MVP4G. – Reduced

Answer 2

I'm currently working on a small website written in GWT using Sring(For Security and Dependency injection) at the backend and GIN at the frontend.

When I migrated to GWT 2.1 I took 1 day to change from my old MVP framework to the integrated one. The example I took as a reference was the one at the GWT website.

Of course it takes you some time to switch, however it results in smaller, cleaner code than with other solutions I've seen
