[Andromda-user] [Bpm4Struts cartridge] [Problem with entity instantiation...] Problem with entity instantiation...

Thu, 09 Jun 2005 06:52:58 -0700 

Hi all!



I got a small project (BPM4Struts and Spring) with two entities: IntranetUser 
and IntranetGroup - IntranetUser has a one-to-many relation to IntranetGroup.

The instantiation of the IntranetGroup works fine, but when I to create a 
IntranetUser I get the following exception.



All values of the new IntranetUser entity are filled with valid objects (of 
type String or IntranetGroup-Entity).



Would be very nice, if somebody could help me...



Kind regards,



Alex



P.S.: The related code:



    protected void 
handleAddUser(sample.intranet.security.AddUserData addUserData)

        throws java.lang.Exception

    {

       IntranetUser userEntity = 
IntranetUser.Factory.newInstance();

       Collection groups = new HashSet(1);

      
 groups.add(getIntranetGroupDao().findGroupByName(addUserData.getGroup()));

       userEntity.setIntranetGroup(groups);

       System.out.println("Username: " + 
addUserData.getUsername());

      
 userEntity.setUsername(addUserData.getUsername());

       System.out.println("Password: " + 
addUserData.getPassword());

      
 userEntity.setPassword(addUserData.getPassword());

       System.out.println("Firstname: " + 
addUserData.getFirstName());

      
 userEntity.setFirstname(addUserData.getFirstName());

       System.out.println("Lastname: " + 
addUserData.getLastName());

      
 userEntity.setLastname(userEntity.getLastname());

       System.out.println("Gender: " + 
addUserData.getGender());

      
 userEntity.setGender(addUserData.getGender());

       

      
 getIntranetUserDao().create(userEntity);

    }
