Catching RPC exceptions at client side
Hi,
Our project uses GWT and App engine. We have a problem with catching
exceptions.
When we define an exception as part of method signature in our RPC
asynch interface and implement it at the server, the client side
catches it and everything works fine.
But in other 'unusual' case we have problems with catching the
exception:
We do some general checks in all our RPC server methods, for example
checking authorization of current user, and if user is not authorized
we throw a specific exception.
For that purpose we have extended the class RemoteServiceServlet and
overridden the method onAfterRequestDeserialized, in this method if
user is not authorized we throw our UnAuthorizedException exception.
The problem is that the client side gets just a general
StatusCodeException with code 500 (internal server error). I have
found this relevant code at RpcCallbackAdapter.onResponseReceived:
.
.
if (statusCode != Response.SC_OK) {
caught = new StatusCodeException(statusCode, encodedResponse);
.
.
The question is how we can get the actual exception in this case? is
there a way for the client to get the returned Response object ? Any
other direction ?
Thanks
Itzik Yatom

External access to CSS resources
Hi, I already use Intensively UIBinder with my GWT projects. Considering if to use also CSS resource or the regular external CSS files in my GWT projects. Since I work with a graphical designer that may need to change the styling while she gets from me initial results and improve them, she should have an access to the CSS, change some rules, save the result and send me fixes. Can I do it while using CSS resources? Thanks Itzik -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

UiBinder styling superseded programmatic styling
When adding the attribute styleName to an UiBinder XML element, GWT translates it to setStyleName method call. The problem is when using a custom Composite class that already has called to setStyleName method, UiBinder supersedes the Composite style. I wish that UIBinder would call to addStyleName instead but I understand that it's based on the entity bean approach. Is there a way to overcome that?

Re: Obsufcated class names when using UIBinder
Thanks Thomas I have it. Although the UIBinder adds a very long prefix, I can see the original class name.

Obsufcated class names when using UIBinder
I have just started to use the the UIbinder in the GWT 2.0 official release, which is a great tool. When I am inspecting DOM elements in firefox using firebug I notice that GWT generates classes names that are different from the original ones. I understand the intention to generates unique class names, but the problem now is that when investigating the page structure it's hard to identify the original elements without their class names. Is there a way to keep the original class names ? Thanks Itzik -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Help - my web site based on GWT fails to load in IE8
It is working! I use Canvas class and it doesn't work in IE8, I have disabled, temporarily, the canvas object and it works. Now I need to find another implementation for what I did with the Canvas.

Help - my web site based on GWT fails to load in IE8
I have just finished to develop a web site that is mostly written in GWT. During a non-trivial load that contains many panels and widgets build, asynchronous server requests for grabbing information from DB and XML file contents, it fails in IE8 on adding the main Composite object to the root panel with unclear JavaScript message. In Firefox and IE7 it works fine. How can I get information about the failure cause ? and this is, actually, a general question - How can I get information where is the failure in my Java classes when at runtime all Java classes are compiled to JS ? It looks like a nightmare when everything works at development environment where you can debug the Java code but it fails on runtime with an error that tells you nothing about the real problem.

Vertical SliderBar
Hello, I want to use the SliderBar (from the Incubator project), I prefer a vertical slider but I can't find a way to change it. Is there a way (using CSS or another) or a variation of this class that allows vertical appearance and not only horizontal?
