Yes, this is true - this is obviously a spec problem. If the submitted value is an object, it should also be allowed to convert it. A converter is more than just a string to object (and back) converter, it is an artefact which transforms information from its representation for output (and this output could be anything, and certainly doesn't have to be string based) to its representation which the business model (or also an artefact within JSF, like a validator) understands. So I agree. This hasn't come up so far cause nobody uses non string based output models for JSF. Note that my notion of a business converter (discussed on this mailing list a while ago) for converting between a business model representation and a representation in a JSF artefact like the renderer (e.g. you use joda.Date in the business model, but the JSF date picker renderer only understands the normal java date) is also hinting in the direction that such an additional converter API would be necessary. I discussed this with the EG (and also Ed privately), and there wasn't much interest for adding this. best regards, Martin best regards, Martin -- http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces
