Hi, hope i could help a bit in researching this. For now i will use my own variant of AnnotationProcessor6.
BTW it was a bit of a mess to create my own version of this class because SourceAnnotationHandler.class has a lot of package private methods which are used by AnnotationProcessor6. So i also needed to clone that class too. grrrr. :-) I am quite sure that there are not that much people out there using the MetaModel feature at all. Because first you need to use Criteria API which is probably also not THAT widespreaded so far. This could be the reason why this bug is not mentioned somwhere. But software development is crazy. You start using Criteria API because its somewhat typesafe in conjunction with MetaModel and now you are fighting with AnnotationProcessor. Not really where we make our money. But on the other hand its a challenge to find out why things break. --- regards Marc Logemann http://www.logemann.org http://www.logentis.de Am 23.03.2011 um 16:55 schrieb Rick Curtis: > Yes that seems reasonable.
