enable validation on file upload component
------------------------------------------
Key: JBSEAM-1981
URL:
http://jira.jboss.com/jira/browse/JBSEAM-1981
Project: JBoss Seam
Issue Type: Patch
Reporter: Bruno Bieth
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).
