Is @StyleBinding supported on @Templated composite components?
A complex UI based on template contains custom components, also build on templates. A modified StyleBoundTemplate.java test case looks like:
@Templated
public class StyleBoundTemplate extends Composite {
@Inject @AutoBound DataBinder<TestModel> dataBinder;
@Inject @Bound @AdminBinding @DataField private Label testA;
@Inject @Bound @TestBinding @DataField private Label testB;
@Inject @Bound @ComponentBinding @DataField private CustomComponent testC;
...
An attempt to implement @StyleBinding on CustomComponent results in error:
java.lang.AssertionError: This UIObject's element is not set; you may be missing a call to either Composite.initWidget() or UIObject.setElement()
at com.google.gwt.user.client.ui.UIObject.getElement(UIObject.java:558)

It looks like templated component method initWidget() in generated BootstrapperImpl.java is called in context.initializationCallback(), but the method addElementBinding() is called before the component is fully initialized.
StyleBindingsRegistry.get().addElementBinding(inj568_StyleBoundTemplate, _$1399813453ComponentBinding_0, _$188674782__600660785_testC(inj568_StyleBoundTemplate).getElement());
The resulting exception is:
java.lang.AssertionError: This UIObject's element is not set; you may be missing a call to either Composite.initWidget() or UIObject.setElement()

How to ensure the custom component is initialized before addElementBinding() is called? Is it safe to move addElementBinding() into initializationCallback() ? Is the initializationCallback() calling order guaranteed, so that inner components inside the template are initialized before main component?
