Hi people: In order to avoid the declaration of DTOs when I try to send my bussines beans to another context (for example, retrieving beans with Remote EJB or Web Remoting). In order to check security constraints, I would like to exclude properties depending on the permissions of the user logged on, mixin the way as @WebRemote and @Restrict works. I would like to annotate my Entities in the next way: @Name("person") class Person implements Serializable{ .... @SerializeWhen("#{s:hasPermission('manager')}") List getFriends(){....} } We can detect "Serialization Gateways", like an EJB remote call or WebRemote call, and perform an implicit invocation of a "serializeWithRestrictions()" method to serialize only the permissed properties. Are there a way to perform a checking like this in Seam? Thank You! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4102329#...
