Hi Michael, If you could elaborate a little more on which part of deferred binding you're not sure about, that would help pinpoint the problem you're having and setup deferred binding code for your mobile browser target.
In general, however, the way deferred binding works is by defining the rules for the deferred binding using replacement (see doc link below), creating the default and the mobile classes that should be used for the desktop browser and mobile browser versions of your widget, respectively, and then creating your widget via the GWT.create(MyWidget.class) call to have the compiler create bindings for the mobile target. Deferred Binding using Replacement: http://code.google.com/webtoolkit/doc/1.6/DevGuideCodingBasics.html#DevGuideDeferredBinding For an example, check out the inner workings of the PopupPanel widget. You'll notice that the PopupImpl instance belonging to the PopupPanel class is created using the GWT.create(PopupImpl.class) call. Looking at the deferred binding rules for the PopupPanel in the Popup.gwt.xml file (contained in the gwt-user.jar), you'll see that the following rules are defined: <!-- Fall through to this rule is the browser isn't IE or Mozilla --> <replace-with class="com.google.gwt.user.client.ui.impl.PopupImpl"> <when-type-is class="com.google.gwt.user.client.ui.impl.PopupImpl"/> </replace-with> <!-- Mozilla needs a different implementation due to issue #410 --> <replace-with class="com.google.gwt.user.client.ui.impl.PopupImplMozilla"> <when-type-is class="com.google.gwt.user.client.ui.impl.PopupImpl"/> <any> <when-property-is name="user.agent" value="gecko"/> <when-property-is name="user.agent" value="gecko1_8"/> </any> </replace-with> You could essentially follow the same pattern for the mobile version of MyWidget.class, perhaps creating a MyWidget.gwt.xml file to contain the deferred binding rules.
