    <p>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:</p> <pre><code>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(); ..... } </code></pre> <p>The Css class is an empty class extending CssResource :</p> <pre><code>public interface Css extends CssResource{ } </code></pre> <p>Then in my onModuleLoad() I use :</p> <pre><code>StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet1().getText()); StyleInjector.inject(ResourceBundle.INSTANCE.stylesheet2().getText()); </code></pre> <p>When I compile I get the following error:</p> <pre><code> Rebinding com.docobo.keswick.keswickweb.client.ClientResources.ResourceBundle Invoking &lt;generate-with class='com.google.gwt.resources.rebind.context.InlineClientBundleGenerator'/&gt;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
