The 3rd patch set adds tests, UiBinder element parsers for DateLabel and NumberLabel, and the ToggleButton (issue 5571) which I forgot in previous patches.
I found some issues with generics in UiBinder and had to relax a check in UiBinderParser (but I believe this is taken care of later on, see the comment in the code, and comments below). In case you fear this delays things too much for the 2.1.1 release; it's possible to split this patch into subparts: 1. everything except ValueLabel et al. (straightforward) 2. ValueLabel and the DateLabel and NumberLabel subclasses (without UiBinder support) 3. UiBinder parsers for DateLabel and NumberLabel 4. UiBinder fix for generics (so ValueLabel's @UiConstructor can be used) http://gwt-code-reviews.appspot.com/1099801/diff/26001/27006 File user/src/com/google/gwt/uibinder/rebind/UiBinderParser.java (right): http://gwt-code-reviews.appspot.com/1099801/diff/26001/27006#newcode267 user/src/com/google/gwt/uibinder/rebind/UiBinderParser.java:267: // Type matching will be checked by UiBinderWriter#maybeWriteFieldSetter This was causing errors with ValueLabel's DoubleRenderer in the UiBinderTest: resourceType were the JGenericType Renderer<T> whereas ownerField's type were either a JRawType or JParameterizedType. There's actually a more subtle issue within BeanParser which prevents using <ui:with field='doubleRenderer' type='com.google.gwt.text.client.DoubleRenderer' /> because the uiField's type for the ValueLabel is ValueLabel<Double> (which accepts a Renderer<? super Double> argument in its ctor) but the ownerFieldClass is the JGenericType ValueLabel<T> (expecting a Renderer<? super T>). I tried changing the ownerFieldClass to uiField.getType() (when uiField is not null *and* its getType().getRawType() is more specific than the 'type' –otherwise the <gwt:Label gwt:StackPanel-text=.../> fails on the text="" attribute because the uiField's type is Widget) but it then fails because the JParameterizedClass renames constructor's argument to "arg0". Overall, there's some improvements needed around generics. http://gwt-code-reviews.appspot.com/1099801/show -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
