Hi all,

I have next problem:

class ProjectDaoImpl


class ProjectDaoService


class Project



class ProjectAction


I don't know why merge is functional only for adding object and not for deleting object . Do you have any idea ?

(EJB3, JBoss 4.2.2,Struts2 - I am newby in ejb 3)

Did you properly override the equals and hashCode methods in RoleAssociation class?? I know this is a basic things, but sometimes we miss some very basic things...
