In retrospect, I'd rather have a one shot process: generate source code so you can tweak it; and when you change your domain model, either you update the proxies by hand, or you re-generate them. And because the sources would be checked in SVN/Git/whatever, you could easily merge/ignore the changes you made that the generator would have cancelled.

The idea is that you always generate the base classes on every build, but you also generate the concrete classes once.

Re: too much code: GWT Development with Activities and Places
i believe the the very nature of GWT's JRE emulation to javascript with combination with java's lack of closures, is the one causes the large code base. this is because the style of writing itself is extremely different then regular java writing. take for example the mandate to write every function call to a server (RPC,JSON,RF etc..) as asynchronous, in other frameworks, you would have no calls to the server, just page reloads, (or jsp forwards), so it not exactly you gave much thought to actual process of calling a server resource, you just did it, it's like blinking, try to focus on each time you blink and becomes very annoying. add to that, that for each AsyncCallBack you have to write an anonymous class (a poor standin for closures, which java scripts DOES have), and you get even MORE code. and speaking of server client, communication, because of the JRE emulation, you discover on many instances you can't really reuse some of the code or models you wrote on the server as they contain features which are not present client side, and the ONLY way to have some sort of linkage between the 2 sides is via use of annotations, so once again, something you took for granted, comes right back at ya. so now you have to double the code for client server models, and use crap load amount of brackets just for fun of it. and when you try to reuse using generics , you find out the hard way that in some cases you have go through lots of hoops just to get that working right, once again because of the nature of GWT compile process. so in a sense one might say that programming java in gwt, is unlike programming in other web frameworks, although the syntax is the same, you have to un-learn something you got used to over the years. so far i see that the current trend is to create generators for the boilerplate codes, via annotations, either to domain models or proxies, and i think that at least to make the work more streamlined google should (off-course) fix major bugs, but also load the GPE with a whole lot more of wizards, generators, re-factoring tools, to bridge this gap between regular java and gwt java, i mean it doesn't even have a wizard for creating RPC's not to mention other calls like request factory. not to mention to COMPLETE lack of ide support the module xml file , but that's another rant entirely. and although i took a look at MVP4G and the likes, the problem is they were created prior to activities and places, so if you that with the current gwt, you actually have 2 frameworks for mvp. also places don't really replace history, i think they actually use it behind the scenes. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: too much code: GWT Development with Activities and Places
I use MVP straight out of the Google videos and docs, and I love it. When I need to swap a view in or out, or change a url structure, or change a bit of communication with the server, I go strictly to the 1-2 files involved, make the changes I need, and never fear that some hidden bug will appear somewhere else. The Places/Activity framework works beautifully, and gives me the flexibility to navigate programmatically in response to events without having to put History-manipulating code anywhere but in my PlaceController. We've got 46,000 lines of GWT code running now, and it's easy to debug, easy to maintain, and is really delivering on the cross-browser compatibility promise. What I love about GWT is how loosely coupled the different frameworks are. I started out with GWT-RPC, and then moved to RequestFactory. Then I wanted to switch to a plain JSON format so that the API could be usable to others w/o RF, and so I chucked most of RF... but I could still use parts of it like AutoBean to make parsing a snap! If I have to pay for this modularity with 3x the code size, I'll do it - I'm a one-man dev team and GWT helped me launch a complex data-processing app in a few months. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

My worry is that I see those valuable resources being applied to new high level architectural concepts which may or may not be useful to users, while nasty reported bugs remain for months or even years in the core functionality. A solid core is critical. I'm don't want to seem unappreciative by adding to a discussion that might be a little critical, but I couldn't agree more strongly with what John said above. I've struggled to get excited about much of the GWT functionality since 2.2 came out and I keep hoping the focus will change back to infrastructure rather than architecture. Core functionality (date/timezone/calendar, drag and drop, etc.) and weird compatibility problems (FireFox key events and similar) seem to languish for so long. Arguably, much of this isn't Google's responsibility, but the vision of GWT as a layer over all the browser craziness implies these areas (along with regular GPE updates, no matter how annoying Mozilla's policies) should be something of a priority. Beyond this, some people seem to make the case that third parties should be filling the gap with various UI widgets, but the lifespan of the various bits of code floating around out there makes using third party parts problematic. I'm amazed at how much pre-2.0, listener- centric code is still out there. I feel like I'm in jungle as soon as I start looking around outside the toolkit. A stable set of core UI widgets (masked text entry, date/time pickers, currency, etc.) would go a long way towards making GWT easy to use to build meaningful apps with a lower learning curve. In a nutshell, I'd have been much more excited to see a healthy list of compatibility fixes and a really nice timezone-savvy date/time picker that I knew would be supported long term rather than all the Roo stuff that came out recently. Not that I don't appreciate everything that's already there, though.

Re: too much code: GWT Development with Activities and Places
Hi, I think future of GWT being threatened by 2 evil: 1. *Big compile time* (specially when size of module increase) which increase development time, and usually in compile time, developer will concentrates on subjects other than development (!) and it takes a few minutes to concentrates on development again. 2. *Complex and excessive code*. For example, I used Spring Roo to generate code for an entity with 4 field (property or relation) based on GWT, Spring Hibernate. It generates about 1600 line code just for CRUD (create-read-update-delete and search) operations (!). Spring Roo generated GWT code based on MVP and ActivityPlaces, UIBinder,... Recently I designed a code generator based on GWT, Spring and Hibnerate. It generates about 700 line code for same entity, same operations and same functionality (but I don't use MVP, PlacesActivities or RequestFactory). So it is possible to decrease complexity and size of code. MVC pattern (predecessor of MVP) which introduced in 1990s by GoV (Buschmann et. al.) as an architectural pattern, but it was not used widely and now simpler versions of it are used. It shows that a complex pattern will not survives even it designed based on best OO principles. MVP is a good pattern but if you used it, you should accept its complexity, So use it when is necessary.

I spent a lot of time on it when starting out, as it was the most prominent documentation on how to do certain things (views and 'pages'/places in particular) for very little net gain. For simple apps, using UiBinder and attaching the resulting widget to the page manually lets you actually get to the meat of your application much faster and with much much less complexity. You can always refactor to MVP later.. (though that doesn't sound fun) anyway just my 2cents, maybe with better tooling there would be fewer of these 'MVP is too complex' threads. And on tooling, and RequestFactory, the new annotation processor is great, compile time validation really helps (I am manually writing my proxies) but I was disappointed to see that the 'RPC tooling' is only for Android Apps.

too much code: GWT Development with Activities and Places
I am trying to understand and adopt the MVP good practices and UIBinder alongside Activities, Places, Hisotry, Views, Presenters What strikes me is there seems to be too much code that does nothing. Place is one example. In the MVP part 1 and part 2 examples we had browser History modelled by a stack of Strings. What I didn't like is the dispatching case / switch statement that compared tokens (history strings) and instantiated new presenters / views. This looked already over the top, plus string constants directly over the code is a big NO- NO. Refactoring history tokens into string constants or if someone is very anal enums should do the trick. I was wrong. Now we have Places instead of string constants. Places have gotten glorified to the level of having their own handler... So now, there is history and places which do the same thing except possibly for places that don't have a history token attached. It looks to me we went from smart-er views / presenters to dumber views / presenters with more anonymous inner classes (for handlers) and confusing wiring boilerplate (MVP p1). MVP p2 saves some of the inner class nonsense but introduces new interfaces for view and presenter. These are supposed to help with development of alternative view implementations ... but honestly I'd rather have a smart view / presenter class that wires everything together. The processing is delegated to event bus or other handler that processes the business logic. Currently my GWT code is 10x larger than my javascript code. And javascript eclipse plugin editors and libratries / frameworks are getting better rapidly. I'd like to see a way to write GWT code that is only as verbose as JS. thoughts?

Re: too much code: GWT Development with Activities and Places
I have no answers, but I fully agree. GWT development is getting horrendously complex.

I agree with you guys completely. Sometimes too strict of an OOP approach can lead to lots of over-engineering.

I have to agree about this here as well, the Request Factory implementation is something that requires a lot of boilerplate code.

Re: too much code: GWT Development with Activities and Places
I've solved a lot of the boilerplate issues by writing an annotation processor to create my Proxies.

Did almost the same, but as a Maven plugin that scans the classpath for classes extending a few base classes.
