    <p>Although you can set the compiler to output 'pretty' code, I suggest you write export functions for the classes you want to call from outside your GWT project. I believe somewhere in the GWT documentation it's detailed how to do this, but I couldn't find it so here an example I just created.</p> <pre><code>class YourClass { public YourClass() { ... } public void yourMethod() { ... } public static YourClass create() { return new YourClass(); } public final static native void export() /*-{ $wnd.YourClass = function() { this.instance = new @your.package.name.YourClass::create()() } var _ = $wnd.YourClass.prototype; _.yourMethod = function() {this.instance.@your.package.name.YourClass::yourMethod()()} }-*/; } </code></pre> <p><strong>EDIT</strong></p> <p>To elaborate, your code will get obfuscated like normal, but thanks to the export function, you can easily reference those functions externally. You <em>don't</em> have to rewrite anything from your Java class in JavaScript. You only write the references in JavaScript, so you can do this:</p> <pre><code>var myInstance = new YourClass(); myInstance.yourMethod(); </code></pre> <p>Of course you have to call the static export method from somewhere in your GWT app (most likely in your EntryPoint) to make this work.</p> <p>More info about referencing Java methods from JavaScript: <a href="http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html#methods-fields">http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html#methods-fields</a></p>

    1. COThis approach would work assuming I am to keep the Java code. I just need a tool to convert Java method to JavaScript function. To save me the trouble of reimplementing the same algorithm in JavaScript.

    2. COBut you could use this method to identify the relevant JavaScript function that the compiler creates. You asked for a predictable naming scheme, and this is it! `window.YourClass.yourMethod` will point you to the new obfuscated name in JavaScript.

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.
