Re: code splitting question
Hello,
It depends on the dependency between your module. The best way to deal with
code splitting is to start it. And than you can analyse each your code
splitting combination. Google provide the tools to do that.

Re: GWT Performance : Good or Bad ?
Finally, I've made my application faster. The idea is not using GridRenderer and prepared the model in the server. For example I write in the server than create an Image object in the client. Like I said, the target application is IE8 (not very performance), and by doing this I managed to reduce the grid loading time to almost a half. Hope this help.

Re: GWT Performance : Good or Bad ?
Stevko, Yes I'm aware of that too, but I think is not the problem with caching, is more about how many DOM object generated by GXT. For a simple row in a grid, GXT will produce : a *div ,a table,a tbody, a tr, a td. *And is not only with the Grid. I think that makes GXT heavier than GWT.

Re: rpc call
No I think there is no method that can do that, the RPC is asynchronous.
You should create a callback and retrieveData in the callback instead.

Re: File download and Exception handling using a servlet.
Helo, Well it is a delicate subject to handle. There is no default method to deal with the error result. A way to approach this, is by testing the servlet response. The fastest is to make sure that there is no "ERROR CODE" (404, 503 ...) in resultHtml. But this make your application depends on your servlet container implementation. If you can rewritte your ServletReponse, then you can decide your own error code and how to handle it. Hope this help you, Bowie http://www.html5bydemo.com/ On Mar 12, 11:19 am, Appien wrote: > Hi guys, > > In my GWT application the user can download a PDF file by using a servlet. > To start the download I create in GWT a hidden Frame Object which calls the > servlet.

Hi Khan I would like to say good job on your complete analyse of the problem. Well we have this problem too in our project. But it only occurred in production because of their network latency nature. Have you managed to reproduce it during the test ? If you have, how do you do that ? Regards.
