Updating Hibernate Entites

[Dominik Gätjens]

Hello List,

 

i'm trying to update an Hibernate-Object but alway get an "a different object 
with the same identifier value was already associated with the session:" 
Exception.

 

My Form-Code looks like:

@Inject

      private ConfigurationDAO configDAO;

@Persist

      @Property

      private Configuration config;

 

      void onSuccessFromConfigForm(){

            config.setEditDate(new Date());

            configDAO.doSave(config);

      }

 

      void onActivate(Long configId){

            config=configDAO.doRetrieve(configId,false);

      }

      void onActivate(){

            configs = configDAO.findAll();

            if(config==null)

                  config=new de.leomedia.leotipp.model.Configuration();

      }

 

can anyone give me a lead into the right direction? 

 

thanks, Dominik
