I have a GWT 1.7 application and I want to upgrade it to GWT 2 Milestone 2. The application uses 2 big external CSS files. In GWT 1.7 I had a public folder and put both the CSS files in the folder and my application compiled and worked fine. Now for GWT 2 I have created a ResourceBundle class and put all image sprites and CSS as follows:
public interface ResourceBundle extends ClientBundle {
public static final ResourceBundle INSTANCE = GWT.create(ResourceBundle.class);
@Source("com/web/tech/public/stylesheet1.css")
public Css stylesheet1();
@Source("com/web/tech/public/stylesheet2.css")
public Css stylesheet2();
@Source("com/docobo/keswick/keswickweb/public/images/organisnew.gif")
public ImageResource add_org();
.....
}
The Css class is an empty class extending CssResource :
public interface Css extends CssResource{
}
Then in my onModuleLoad() I use :
StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet1().getText());
StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet2().getText());
When I compile I get the following error:
Rebinding com.docobo.keswick.keswickweb.client.ClientResources.ResourceBundle
Invoking <generate-with class='com.google.gwt.resources.rebind.context.InlineClientBundleGenerator'/>
Creating assignment for gxt_gray()
Replacing CSS class names
[ERROR] The following unobfuscated classes were present in a strict CssResource:
[ERROR] x-tab-scroller-left
[ERROR] x-tab-strip-disabled
[ERROR] ......loads of other styles
Fix by adding String accessor method(s) to the CssResource interface for obfuscated classes, or using an @external declaration for unobfuscated classes.
Following the above instruction when I use @external above all my style classes inside the CSS file I get the following error :
[ERROR] Generator 'com.google.gwt.resources.rebind.context.InlineClientBundleGenerator' threw threw an exception while rebinding 'com.docobo.keswick.keswickweb.client.ClientResources.ResourceBundle'

Try with @NotStrict
. Example:
@NotStrict
@Source("com/web/tech/public/stylesheet1.css")
public Css stylesheet1();
Got it solved. As pointed out by Thomas@Google Groups --> The @external must not be put "above" the style
http://code.google.com/p/google-web-toolkit/wiki/CssResource#External...
The example from this link, the css will look like :
@external .legacySelectorA, .legacySelectorB;
.obfuscated .legacySelectorA { .... }
.obfuscated .legacySelectorB { .... }
/* @external also accepts tail-globs */
@external .myProject-*;
.myProject-text {}
.myProject-foo {}
