Bruno Bieth commented on JBSEAM-1981:
-------------------------------------

Sorry for the com.sun stuff, eclipse added it by mistake when doing autocompletion ... just remove it.
I've formatted the code as well with eclipse (shortcut habit ...)  and changed few methods ... looked better to me to just post the whole file.

> Currently file upload can't be validated. 
> The attached patch allow to use the hibernate validation framework with byte[] attribute.
> You may have, for instance, to check if an uploaded file is an Image.
> About the patch :
> First the submittedValue is not set so the validation phase is skipped, second file upload doesn't use the standard "value" attribute (needed by the ModelValidator) but "data".
> To work you have to use a value attribute to your fileupload component. At the moment this work only with Facelets. For backward compatibility the data attribute is kept (but validation won't work).
