In lieu of an up-to-date Developer Guide and release notes, below are the major highlights relative to GWT 1.5.3. *** New Project Structure in GWT 1.6 *** One of the biggest changes to GWT 1.6 is a new project structure. The old output format has been replaced by the standard Java web app expanded war format, and the actual directory name does default to /war. Note that the war directory is not only for compiler output; it is also intended to contain handwritten static resources that you want to be included in your webapp alongside GWT modules (that is, things you'd want to version control). Please also note that the GWTShell and GWTCompiler tools will maintain their legacy behavior, but they have been deprecated in favor of new HostedMode and Compiler tools which use the new war output. When 1.6 is officially released, we will be encouraging existing projects to update to the new directory format and to use the new tools to take advantage of new features and for compatibility with future GWT releases. The sample projects provided in the GWT distribution provide an example of correct new project configurations. For more details on the specifics of the new project format, please see GWT 1.6 WAR design document (http://code.google.com/p/google-web-toolkit/wiki/WAR_Design_1_6). A couple of important changes we should highlight here: - Projects with server-side code (GWT RPC) must configure a web.xml file at /war/WEB-INF/web.xml. This web.xml file must define and publish any servlets associated with the web application. See the included DynaTable sample. Additionally, server-side library dependencies must be copied into /war/WEB-INF/lib. For example, any GWT RPC servlets must have a copy of gwt-servlet.jar in this folder. - HTML host pages will no longer typically be located in a GWT module's public path. Instead, we'll be recommending that people take advantage of the natural web app behavior for serving static files by placing host pages anywhere in the war structure that makes sense. For exmaple, you might want to load a GWT module from a JSP page located in the root of your web app. To keep such handwritten static files separate from those produced by the GWT compiler, the latter will be placed into module-specific subdirectories. Any page that wishes to include a GWT module can do so via a script tag by referencing the GWT-produced module.nocache.js script within that module's subdirectory. As of 1.6, we'll be recommending that only module-specific resources used directly by GWT code, such as image files needed by widgets, should remain on the public path. See the included Showcase sample for some examples of this distinction. - When you do need to load resources from a module's public path, always construct an absolute URL by prepending GWT.getModuleBaseURL(). For example, 'GWT.getModuleBaseURL() + dir/file.ext'. This advice has not changed, but in the past it was easy to be sloppy with this, because the host page and GWT module typically lived in the same directory, so using a relative URL would usually do the right thing. Now that GWT modules live in a subdirectory, you must reference public resources through GWT.getModuleBaseURL(). *** Hosted Mode Enhancements *** Although the legacy GWTShell still uses an embedded Tomcat server, the new HostedMode runs Jetty instead. There is also a new Restart Server button on the main hosted mode window. Clicking this button restarts the internal Jetty server, which allows Java code changes to take effect on the server without having to completely exit and restart hosted mode. This is useful when making code changes to RPC servlets, or when serializable RPC types are modified and the server and client are out of sync. *** New EventHandler System *** Event handlers have been added to replace the old event listeners used by Widgets, History, and various other classes. The new system has a few differences from the old system: - EventHandler methods always take a single parameter: the GwtEvent that the Widget fired. For example, ClickHandler has a

Re: Best image preloading practice?
Well, I know prefetch is working to some extent (at least, in Chrome and Firefox), as I can watch it prefetching rather large volumes of images that arnt used in the html at all. All of those images must have been triggered by the prefetch loop. Still, I'll read over the Mozzilla doc, maybe things have changed a little since javascript has been more widely used. On Feb 6, 3:12 pm, gregor greg.power...@googlemail.com wrote: @Litty: yes, I think you are right, my ignorance. Image.prefetch() will causes the image to be loaded into browser cache. You then use the same URL to instantiate an Image object later in code, and hopefully the image binary will be already downloaded. This old Mozzilla doc describes the process: http://devedge-temp.mozilla.org/viewsource/2003/link-prefetching/inde... The doc suggests the behavior darkflame described in OP, namely, browser is busy downloading all the prefetches it finds in the page. @darkflame: b) If I do have to load, say, upto 10 images that have to be seperate, is it better to just loop over a list of them prefetching and leave it upto the browseror should I put a timer and trigger a load every, say, 5 seconds ? (or dosnt it make much difference). My reading of the Mozzilla doc is that the browser will notice all the prefetch tags when it loads the page, and it will then get busy downloading them. So I have doubts whether where you put the Image.prefetch(url) in execution logic makes any difference, i.e. you do not have fine tune programmatic control over prefetch so you can't code to prefetch first 10, then later trigger prefetching next 10. For example the Mozzilla doc states The link tag has to be inside the head tag to make prefetching work etc. On Feb 6, 9:14 am, Litty Preeth preeth.h...@gmail.com wrote: You are thinking of loading 20MB of images into the DHTML DOM of you application Am I?

Hi,
Your class has to implement the interface

Maybe this default constructor misses ?

Re: Announcing GWT 1.6 Milestone 1
Hi - I've perused the WAR Design document, but I've several questions that
remained unanswered.
In my project, we use GWT-SL and Gilead - the former for exporting Spring
beans as GWT-RPC services, and the latter for transferring Hibernate-enabled
objects back and forth between the server and client.
A consequence of using GWT-SL is that I no longer map my servlets through
web.xml - instead, I've a springDispatcher servlet which receives all
requests and routes them to the appropriate service exports I've defined
with GWT-SL, using the SimpleUrlHandlerMapping which Spring provides.
Now, since I'd like to route only GWT-RPC (and servlet) requests through the
Dispatcher servlet, I've only routed /services/* to it.
The difficulty arises when using Hosted Mode. First, I have to copy a
modified web.xml to ${project}/tomcat/webapps/ROOT. This web.xml routes all
requests to /services/* to my springDispatcher. This web.xml is different
than the one I distribute with my WAR, since it also includes mapping for
the GWTShellServlet. Also, in order for serialization to work, I have to
compile my project once (using GWTCompiler) and copy all resulting *.gwt.rpc
files to ${project}/tomcat/webapps/ROOT/${module}/. This occurs because the
GWTShellServlet generates these dynamically as GWT-RPC requests arrive.
I've semi-automated the whole process using Ant tasks, and I'm aware of the
gwt-maven plugin which provides some of this functionality, but I'd like to
know whether the situation has been fully or partly addressed with the 1.6
release.

Doing AOP, Dojo style
I'm a huge fan of GWT, but I'm also a big fan of development methodologies, like Inversion of Control and Aspect-Oriented Programming. IoC and AOP are two concepts I've struggled to work into the GWT framework since day one, with AOP being a bit more difficult to achieve than IoC, in my opinion. I recently came across the Dojo Toolkit, which includes, among other things, a facility for advising your code, AOP style: http://svn.dojotoolkit.org/src/tags/release-1.2.3/dojox/lang/aspect.js After digging into it, it appears to take advantage of the dynamic nature of the JavaScript language, swapping out implementations of advised methods at run time with wrapper functions. All-in-all, I think this is a rather brilliant approach, and it's something I'd love to see supported in GWT. The only problem I see is how to go about crossing that dynamic bridge that, at first glance, appears to be the kind of thing Java and GWT might not work well with. Of course, deferring to native code implementation is an option, but that seems to defeat the purpose of the compiler's advantages.

Re: Announcing GWT 1.6 Milestone 1
Hi, I am interested to migrate from the 1.5.3 to the 1.6.0 M1. When I use this M1 with -war option, the the compiler output is not like an expanded war. I tried to specify all parameters (-war, -gen, - extra ..) without success. The output of the compiler is always similar to the output of the 1.5.3 compiler. The compiler indicates the 1.6.0 version, so I am sure to use the 1.6. I am under linux (ubuntu). Do you have any idea why the compiler output is not like an expanded war ?

Note that the war directory is not only for compiler output; it is also intended to contain handwritten static resources that you want to be included in your webapp alongside GWT modules (that is, things you'd want to version control). Please also note that the GWTShell and GWTCompiler tools will maintain their legacy behavior, but they have been deprecated in favor of new HostedMode and Compiler tools which use the new war output. When 1.6 is officially released, we will be encouraging existing projects to update to the new directory format and to use the new tools to take advantage of new features and for compatibility with future GWT releases. The sample projects provided in the GWT distribution provide an example of correct new project configurations. For more details on the specifics of the new project format, please see GWT 1.6 WAR design document (http://code.google.com/p/google-web-toolkit/wiki/WAR_Design_1_6). A couple of important changes we should highlight here: - Projects with server-side code (GWT RPC) must configure a web.xml file at /war/WEB-INF/web.xml. This web.xml file must define and publish any servlets associated with the web application. See the included DynaTable sample. Additionally, server-side library dependencies must be copied into /war/WEB-INF/lib. For example, any GWT RPC servlets must have a copy of gwt-servlet.jar in this folder. - HTML host pages will no longer typically be located in a GWT module's public path. Instead, we'll be recommending that people take advantage of the natural web app behavior for serving static files by placing host pages anywhere in the war structure that makes sense. For exmaple, you might want to load a GWT module from a JSP page located in the root of your web app. To keep such handwritten static files separate from those produced by the GWT compiler, the latter will be placed into module-specific subdirectories. Any page that wishes to include a GWT module can do so via a script tag by referencing the GWT-produced module.nocache.js script within that module's subdirectory. As of 1.6, we'll be recommending that only module-specific resources used directly by GWT code, such as image files needed by widgets, should remain on the public path. See the included Showcase sample for some examples of this distinction. - When you do need to load resources from a module's public path, always construct an absolute URL by prepending GWT.getModuleBaseURL(). For example, 'GWT.getModuleBaseURL() + dir/file.ext'. This advice has not changed, but in the past it was easy to be sloppy with this, because the host page and GWT module typically lived in the same directory, so using a relative URL would usually do the right thing. Now that GWT modules live in a subdirectory, you must reference public resources through GWT.getModuleBaseURL(). *** Hosted Mode Enhancements *** Although the legacy GWTShell still uses an embedded Tomcat server, the new HostedMode runs Jetty instead. There is also a new Restart Server button on the main hosted mode window. Clicking this button restarts the internal Jetty server, which allows Java code changes to take effect on the server without having to completely exit and restart hosted mode. This is useful when making code changes to RPC servlets, or
Re: any advices to make gwt applications look nicer/
Hi, - First, I suggest you to use SmartGWT. GWT ext will not evolve lot due to ext licence. GXT is not free and today it does not offer enough widgets than smart GWT. - Second you have to play with CSS. For the last point I advice you to define an interface containing style definitions (String field representing the style name). - If after that you are not happy, you should get a web designer ;-) Regards, Seb On 8 fév, 14:03, ytbryan ytbr...@gmail.com wrote: hi all, is there a specific way to create nicer and more quality gwt application? i do know about mygwt and gwt ext. but is there other ways? thank you any advices are welcome. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWTShell crashes quickly under ubuntu with 64bit processor
Hi, I am using GWT 1.5.3 version. Since 3 years I worked with GWT under linux (ubuntu 8.10) with a 32 processor. Since few days I have a new computer with 64bit processor (ubuntu 8.10 again). My project works well in compiled mode. But at each time, I use the simulator (GWTShell), it crashes quickly after some actions. I tried to change the java version or runtime without sucess. The crash is a classical JVM crash. I have flash animations in my gwt application. Then I integrated the flash plugin into the mozilla 1.7.12 provided with the GWT ditribution.

Drag and drop problematic with firefox ie
Hi, I'm trying to use my own implementation of drag and drop in a Tetris- like game: http://www.numbrosia.com (not Numbrosia, but you can play it there) It seems ok on Chrome, but Firefox and IE seem to have their own idea of what drag and drop should do that interferes with my implementation of drag and drop. For example, Firefox will actually try to drag and drop a square on its own (even though the squares are not images) and show a circle with a line through it (indicating that you can't drop the square in that position). How do I disable Firefox and IE from attempting to drag and drop their own way?

Re: GWT 1.6 preliminary exploration and doc wish list
The GWT team is happy to announce the availability of 1.6 Milestone 1! Binary distributions are available for download directly from GWT's Google Code project. Happy coding, Scott, on behalf of the GWT team Greetings: Thanks for the tremendous efforts from GWT team and supporting communities. Here are some preliminary exploration and wish list of the coming doc: 1) Using the webAppCreator (ant 1.7.0, jdk 1.6) i create an application, run the hosted mode, then the build to compile the app. In the app war directory, i see the hosted.html and app.nocache.js, but Not the .css and .html file as listed in the compiler output of the StockWatcher 1.6 example. 2) The current gwt-incubator_1-5_Dec_28.jar is not compatible with GWT-1.6.0. Hope the new compatible version will be out soon. I am still working through the examples to understand the new war structure, especially the project that uses different modular GWT modules and the location of public files for different modules. Some documentation and suggested best practices may be required. 3) With new GWT Event Handler, the stockwatcher example shows a container class to use a single handler method for event (ClickHandler) coming from different event publishers (but1 and but2). GWT team may share its experience and approach for all GWT event types in 1 container class, especially the way to integrate GWT event handler with OpenAjax Hub, leveraging GWT JSO and coming UIBinder ;-) 4) In the doc Articles and Tutorials, i see GWT for JSON Mashups and Application of Facebook. It may be a good idea to centralize in 1 place possible GWT applications and how-to to leverage Google API and facilities: Gears, AppEngine, google-ajax-examples, etc. Thanks Duong BaTien DBGROUPS and BudhNet --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

I particularly bumped up Issue #1433 so the team gets to take a look at
investigating it before a final 1.6 release. It seems like having support

I agree.
Finally having said that, you know our motto, Patches welcome!.
I know. I started adding

in RichTextAreaImplStandard that works in Mozilla, but sadly I don't
have resources/capacity to do and test the same in other browsers.

Re: how to access objects from another frame?
Is there a reason why you cannot implement this using a single frame containing two GWT scroll panels. In one pannel is all your regularly refreshing content, in the other is the content the user is interested in. This way your object model is shared across the application and there is only a need for one. You are correct in your understanding of entry points. One entry point specifies on GWT application. Using multiple frame would require multiple GWT applications. You could potentially share data across the applications using native javascript. But this seems like a very complex and error-prone implementation to me. Keeping your whole user interface in one application is the most logical and simplest approach.

Re: Best image preloading practice?
I have only skimmed this thread, and I've not looked at the game, but here is my 2c. my situation is a little different - I'm not pre-loading images per se, but I am loading them in the background. I use a hidden panel (hidden by being positioned off screen rather than display:none) which I load images onto. each image has a load listener so that I can process it when it arrives and move it to the appropriate part of the DOM. on to your problem. could you maintain an array of image URLs, load the first image, attach a load listener and attach it to a hidden panel? when the image has loaded, repeat the process to load the next one. that way, you ensure that they only load one at a time (less blocking behaviour in the browser). once you know an image has been loaded, you are free to use new Image(url) and know reliably that the image will be loaded from cache.

This old Mozzilla doc describes the process: http://devedge-temp.mozilla.org/viewsource/2003/link-prefetching/inde... The doc suggests the behavior darkflame described in OP, namely, browser is busy downloading all the prefetches it finds in the page. @darkflame: b) If I do have to load, say, upto 10 images that have to be seperate, is it better to just loop over a list of them prefetching and leave it upto the browseror should I put a timer and trigger a load every, say, 5 seconds ? (or dosnt it make much difference). My reading of the Mozzilla doc is that the browser will notice all the prefetch tags when it loads the page, and it will then get busy downloading them. So I have doubts whether where you put the Image.prefetch(url) in execution logic makes any difference, i.e. you do not have fine tune programmatic control over prefetch so you can't code to prefetch first 10, then later trigger prefetching next 10. For example the Mozzilla doc states The link tag has to be inside the head tag to make prefetching work etc. On Feb 6, 9:14 am, Litty Preeth preeth.h...@gmail.com wrote: You are thinking of loading 20MB of images into the DHTML DOM of you application Am I?

They are also complicated widgets. I would consider as an alternative breaking up the structure into three widgets, for example: 1. A list of Accounts (Acc No) to pick from left side (a HorizontalPanel basically). 2. A standard Tree widget representing Account Name nodes at top level with the rules and tests nested underneath located top right 3. A leaf data panel to show details of a particular test or rule selected from the Tree, located bottom right. You could use HorizontalSplitPanel and VerticalSplitPanel to divide up the display giving much more flexibility to the user's view of the data, and I think you may find it looks a lot better and is easier to use. There are other alternatives involving DisclosurePanels etc. This approach may not only be easier for the user, but you may find it a lot easier to code as well. regards gregor On Feb 6, 3:48 pm, Arul arulmanikandan.sriniva...@gmail.com wrote: Hi Gregor, I some how managed GWT component as replacement of my presentation layer. currenlty my application will be displaying like tree structure as menu in the left hand and selecting each link its content is diplayed in right side in grid with rows and columns.

Re: Announcing GWT 1.6 Milestone 1
Hi,
I take a look on the build.xml of samples. I didn't see any special
difference.
Here is a part of my build.xml :
java maxmemory=1200m classname=com.google.gwt.dev.Compiler
fork=true failonerror=true taskName=gwtc
arg value=com.raisepartner.prism.PRISM /
classpath
pathelement location=src/main/

[gwtc]Compiling 10
permutations
[gwtc] Permutation compile
succeeded
[gwtc]Linking into
war
[gwtc] Link
succeeded
[gwtc]Compilation succeeded --
483,002s
The output is 'war' directory at the root of my project. This
directory contains only the module directory. There is no WEB-INF
directory created. Is it the expected behavior ?
By looking the samples I understand that my main html page (the one
calling the nocache.js) must me copied manually at the root of the war
directory. The content of the module.public is copied into war/
module. I expected the content would be copied at the root of the
'war' directory.
So my conclusion is that there is no change compared to the
1.5.3 ... :-(

Greetings GWT developers,
The GWT team is happy to announce the availability of 1.6 Milestone 1!
Binary distributions are available for download directly from GWT's Google
Code project.
http://code.google.com/p/google-web-toolkit/downloads/list?can=1q=1.6.0
As always, milestone builds like this are use-at-your-own-risk. There are
known bugs, and it definitely isn't ready for production use. Please
expect
some trial and error getting everything to work. The javadoc that comes
bundled with the distribution should be up-to-date, but the online
Developer
Guide (http://code.google.com/docreader/#p=google-web-toolkit-doc-1-6) is
still very much a work in progress. We will be updating it over the next
several weeks. In lieu of an up-to-date Developer Guide and release notes,
below are the major highlights relative to GWT 1.5.3.
*** New Project Structure in GWT 1.6 ***
One of the biggest changes to GWT 1.6 is a new project structure. The old
output format has been replaced by the standard Java web app expanded
war
format, and the actual directory name does default to /war. Note that
the
war directory is not only for compiler output; it is also intended to
contain handwritten static resources that you want to be included in your
webapp alongside GWT modules (that is, things you'd want to version
control). Please also note that the GWTShell and GWTCompiler tools
will
maintain their legacy behavior, but they have been deprecated in favor of
new HostedMode and Compiler tools which use the new war output. When
1.6
is officially released, we will be encouraging existing projects to update
to the new directory format and to use the new tools to take advantage of
new features and for compatibility with future GWT releases.
The sample projects provided in the GWT distribution provide an example of
correct new project configurations. For more details on the specifics of
the
new project format, please see GWT 1.6 WAR design document
(http://code.google.com/p/google-web-toolkit/wiki/WAR_Design_1_6).
A couple of important changes we should highlight here:
- Projects with server-side code (GWT RPC) must configure a web.xml file
at /war/WEB-INF/web.xml. This web.xml file must define and publish any
servlets associated with the web application. See the included DynaTable
sample. Additionally, server-side library dependencies must be copied into
/war/WEB-INF/lib. For example, any GWT RPC servlets must have a copy of
gwt-servlet.jar in this folder.
- HTML host pages will no longer typically be located in a GWT module's
public path. Instead, we'll be recommending that people take advantage of
the natural web app behavior for serving static files by placing host
pages
anywhere in the war structure
Re: ScrollPanel maxWidth or maxHeight?
I see, I will try it - thank you all for your help. On 6 Feb., 19:32, gregor greg.power...@googlemail.com wrote: Oh right... I think you've got to make sure that the whatever the ScrollPanel contains has actually reduced in size already - if it hasn't the ScrollPanel will refuse to cooperate (i.e. it won't squash it's contents by itself). Then you need to reset it to 1px more than the height/width of its contents (1px is fine if contents is now 0) in order to get rid of the scroll bars (0px etc is ignored as I recall). It won't do that by itself. After that you'll have to try things out - I've always reset ScrollPanel's to a specific height after this procedure, so I don't know how to release it from the 1px instruction without specifying another. I think I would use debugger to find out exact style properties of ScrollPanel whilst it's in growing mode to start with, and attempt to replicate that. If it has nothing in height/width you may have a problem because, as you say, you may not be allowed to actually remove a style attribute once it's there, only modify it, in which case the ScrollPanel may stubbornly refuse to cooperate. You might be forced to attempt a detach of the items widget, replace ScollPanel with a new one, and reattach the items widget to it, or some such... or you might consider another way to do this altogether - ScrollPanel's can be tiresome, uncooperative widgets at times ;-) On Feb 6, 3:46 pm, Davsket g.ave...@gmail.com wrote: well, at least replace it.. On 6 feb, 10:41, alex.d alex.dukhov...@googlemail.com wrote: Haven't found one either. But checking height while adding elements is ok - have it almoust working already. Well, almoust - the problem is that when height or width properties are set once, you can't take it back. So, while panel shows the desired behaviour while adding elements, it remains big when elements are removed. I've already tried: scrollPanel.setWidth(); scrollPanel.setWidth(null); but no luck. I've also tried to set the style-attribute directly with DOM.setStyleAttribute(scrollPanel.getElement(), width, ); but no luck either. Sadly, i haven't found a removeStyleAttribute-method. Any ideas?

The latter, no browser event available AFAIK. I have looked in vain for a general method to get ScrollPanels to resize and generally behave by themselves. I think the reason is that individual divs/table cells etc do not generate events when their size changes. ScrollPanel is basically a div with an overflow setting. I have supposed this is because there can be hundreds if not thousands of boxes on a page, so if they all emitted an event every time they changed their width/heights the browser's event queue would be brought to its knees.

If what you mean is that you want a panel to start at a minimum size, then grow as things are added to it, but then to stop growing and go into scroll mode at a certain point, exactly what i meant. I do not think that is realistically possible since there is no event you can listen for that would tell you when the panel had grown to a given height. You can listen for the browser window changing, but not for an individual panel. I suppose one approach might be to set up a timer to check the current height at intervals and take appropriate action when it hit the limit, but this sounds very inefficient. Indeed it does. I kind of hoped somebody will have a genious idea about it ;-) Thank you for your input anyway. regards gregor On Feb 5, 9:29 am, alex.d alex.dukhov...@googlemail.com wrote: Hi folks, I'm trying to impelement a scrollpanel that becomes bigger (height) to the certain size (maxHeight) when populating it with data.

when I run MyApplication-shell command
I got click me button.
But when i click on click me button I got following exception.

[gwt-contrib] Re: Doing AOP, Dojo style
Hello Jarrod I have implemented an IOC and AOP framework for GWT - rocket-gwt - everything is defined in a Spring like xml file and the factory realised at runtime via a generator. I am however after looking back not convinced of the need for AOP in a GWT environment because of the extra crap that is needed to support the idiom. Basically the following operations need to be supported to emulate the AOP alliance interfaces. - Unwrapping parameters into an array. - Invoking interceptors passing the array of parameters. - At the end of the interceptor chain one needs an adapter to invoke the original method after re-wrapping the parameters. Attempting to emulate the AOP alliance interfaces ( my versions are almost identical copy with minor diferences - eg I pass the method name instead of java.lang.ref.Method instances) adds a lot of bloat because of the need to generate classes to support for each and every targetted class. Any solution that attempts to emulate reflection for the GWT runtime will result in the same need for generated types. If you want look at my tests after turning the compiler option to keep generated classes and you can take a look at what im describing above. Implementating a Spring like IOC container with support for all the basic interfaces (InitializingBean, FactoryBean etc ) with support for all the different lifecycle interfaces also requires a lot of generated classes. Again take a look at the generated classes for further details. To reduce the noise one needs to chop out or simplify features considerably. But then again who wants to write an interceptor that doesnot have access to the target method arguments, types or name ? Im not convinced of the value in such a case. hth On Mon, Feb 9, 2009 at 6:11 AM, Arthur Kalmenson arthur.k...@gmail.comwrote: Hello Jarrod, If you're looking for a Dependency Injection framework for the client side, look no further then Google GIN: http://code.google.com/p/google-gin/. It's essentially a Guice implementation on the client side.

IoC and AOP are two concepts I've struggled to work into the GWT framework since day one, with AOP being a bit more difficult to achieve than IoC, in my opinion. I recently came across the Dojo Toolkit, which includes, among other things, a facility for advising your code, AOP style: http://svn.dojotoolkit.org/src/tags/release-1.2.3/dojox/lang/aspect.js After digging into it, it appears to take advantage of the dynamic nature of the JavaScript language, swapping out implementations of advised methods at run time with wrapper functions. All-in-all, I think this is a rather brilliant approach, and it's something I'd love to see supported in GWT. The only problem I see is how to go about crossing that dynamic bridge that, at first glance, appears to be the kind of thing Java and GWT might not work well with. Of course, deferring to native code implementation is an option, but that seems to defeat the purpose of the compiler's advantages. Any suggestions on this? -- mP --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
