Gerhard Petracek commented on EXTVAL-47:
----------------------------------------

it will be possible with the jsr 303 integration module of extval x.x.3 (the next release) which will be available for jsf 1.1.x. 1.2.x and 2.0.x

so there will be the following validation modules:
 - property-validation
 - bean-validation

however, if you have a nice idea for special extval constraints which perform class based validation, please setup a proposal e.g. at:
http://wiki.apache.org/myfaces/Extensions/Validator/DevDoc/Drafts

> How is it possible to do class based validation as in jsr 303. As far as I understand jsr 303 is validating a populated bean while jsf is validating before population - hence all those issues.
> How about adding another phase for validation after model update? keeping the model valid at all times is a nice feature. But when you create a bean - a customer or what ever - it will be empty at first and surely not valid.
