There is no "out of the box" way of rendering form-properties in JSF. We only have this kind of support for Vaadin. However, if you know a thing or 2 about JSF, it shouldn(t be easy to include/render JSF-tags based on the "type" and configuration of the various supported FormProperty types.
If you call formService.getTaskForm(…), you'll get a list of form-properties containing everything you need to render JSF-elements…
