Re: To smart GWT or not
We install an application in production environment using 2.x GWT GWT- EXT 2.0.5. I tried to migrate to the Smart Gwt but we would have much trouble with the widgets you customized. A new application would have to be developed. We believe that GWT-EXT was easier to use. A basic problem we faced was with the grid that looks different in IE and Firefox.

First of all let me acknowledge that it is very good library with lot of cool and fantastic features. I experimented with it and liked it and planning to use it in one of my project.But I have some doubts and questions , which you I thought you will be best person to answer . Hence this mail. 1. I am using GWT and want to use some Smart GWT widgets in that application.But it looks like I have to include lot of Smart client JS file which size is about 2MB. Client need to download all these JS libs above our GWT compiled script. this become very huge download for client, Even I want to use Smart GWT's grid , I realized that I have to include almost everything except few small smart-client JS.So my question is why is so and what is work around for it? 2.Second, smart-client scripts are not in compressed format (like GWT is). it is like GWT pretty format. If it is compressed then size of all script files will be reduced. 3. My third question is - Why smart GWT is not written in GWT so that it can take advantage of GWT's optimised java script compiler.Smart GWT widget the can be extended by user to customize it. Right now Smart GWT widgets are just black box for developer. Theses are few question I had in mind., Over all features provided by smart GWT are great.

Considering the depth and breadth of features provided by the framework this is a pretty low number of defects. 3 of the 7 issues that you filed were invalid, and 2 defects that were fixed and the remaining 2 were marked WontFix since they were trivial pieces of functionality that the user could easily implement. http://code.google.com/p/smartgwt/issues/list?can=1q=reporter:jarosl... http://code.google.com/p/smartgwt/issues/list?can=1q=reporter:jarosl...And when you were advised how to implement a warning dialog before record deletion on this issue that you filed ( http://code.google.com/p/smartgwt/issues/detail?id=325), you responded by you are sad.

(Like I said before, this particular experience with SmartGWT is one year old.) With GWT the start might be slower but you can predict the deadlines + you're not working with 'black box'.

Does anybody knows why GWT-EXT 2.0.5 doesn't work with GWT 2.1? In my application with GWT 2.0.x, GWT-EXT works fine but, with 2.1 some custom widgets simply don't appear on screen...

Re: Problem using Reflection and Casting objects on GAE
Hi Alex, How about post the solution here for the entire group? :-) On 16 ago, 11:12, AlexG alexander.gauss.ax...@googlemail.com wrote: Hi again, I solved the problem, and now it works, as intended :) If somebody has any questions, how this works, just eMail me. Greets Alex On 16 Aug., 15:37, AlexG alexander.gauss.ax...@googlemail.com wrote: Hi, first thanks for your fast reply. I think this should work. Perhaps I should just give more background information. The App is build using the MVP Pattern. I have one main-Page, with 3 Panels (3 div-elements in the .html) Two of the three panels will never change during runtime. These contains the menu control-widgets. If i select something, then the content-Panel should load the requestet UI (Module). This means, it should load just a new MVP-View via a new MVP presenter. The views and presenters are seperated in extra Projects in Eclipse, just to make it easy to maintain the App. So I definitely don´t want anything in one Project, or any widget in one onModuleLoad(). I also don´t want lots of if´s to decide, which view should be shown, because the app must be highly maintainable, reusable and extensable. By-the-way, the way I do it, works, if I code it with many if´s. But I think this is a dirty solution, and not what I want. Thanks, for your suggestions anyway. Maybe you got asnother idea?? Thanks. Greets Alex On 16 Aug., 14:49, André Moraes andr...@gmail.com wrote: This aproach will not work, since after compiled GWT generates pure JavaScript. You could do the following: 1- Create an JSP page (index.jsp) and use this page as your GWT hosted page. 2- When rendering the page, check the name of the module (not the name of the class) that you want to load. 3- Create one Module.gwt.xml file for each of the user interface that you want to load. 4- When renderinhg the script tag that loads your selection script, change the name of your selection script based on the information that you retreived from the datastore. This options generate lots of files in your GAE application, because each UI will be compiled independ of another, but its fast. Another option will be: 1- Write your GWT application with all the UI and only one entry point class. 2- Create an jsp and define a cookie with the name (not the classname, GWT doesn't have reflection) of the UI that you want to load. 3- Inside your onModuleLoad function, write a series of if's that will check this cookie and load the UI that you want. 4- Use the GWT.async (code-splitting) to load the UI that you want, this will cost another round-trip but will download much less code. If you don't do that, the browser will download all the code for all the UI.

Re: Detect browser back or forward button clicked
Well, in fact you don't disable the buttons.
In the disableFunctionKey.js file, the function just intercept the
keydown or keypress
and return a value tha is not the expected by the browser.
As I wrote, maybe you can find a solution that intercept the browser
back button click.
