Re: extend UiBinder engine

Hi Jens,

Thanks for your answer, I didn't see you did.

I visibly don't need to rewrite the UiBinderGenerator, there's space left for non generating a field in com.google.gwt.uibinder.rebind.FieldWriter : it's specified in the javadoc

The weired thing is that I don't understand from the comment  (In the rare case that you need a field not to be initialized, initialize it to "null".)

what they want me to initialize to null: it's clearly visible in the implementation com.google.gwt.uibinder.rebind.AbstractFieldWriter.write(IndentedWriter)  that if initializer is null, the code generation defalts to GWT.create

 public void write(IndentedWriter w) throws UnableToCompleteException {

    if (written) {

      return;

    }

    for (FieldWriter f : needs) {

      f.write(w);

    }

    if (initializer == null) {

      JClassType type = getInstantiableType();

      if (type != null) {

        if ((type.isInterface() == null)

            && (type.findConstructor(new JType[0]) == null)) {

          logger.die(NO_DEFAULT_CTOR_ERROR, type.getQualifiedSourceName(),

              type.getName());

        }

      }

    }

    if (null == initializer) {

      initializer = String.format("(%1$s) GWT.create(%1$s.class)",

          getQualifiedSourceName());

    }

You would need to extend (or even replace) UiBinderGenerator and then use deferred binding like in UiBinder.gwt.xml to use your custom UiBinderGenerator.

However I would find it a lot easier to write an annotation processor that generates a class next to your UiBinder java file and that contains the code to setVisible(true/false) your UiFields.
