reattaching entities to stop detached entity exception

[tony.herstell1]

Using PickingList (on a Seam project) I found that I had to re-attach all the objects that were used in the component (see code later). I hope that is what you expected to happen.

I did also have to convert the EntityManager to a Seam managed one to get convertEntity to work.

this.classEntity.setSponsors(reattachUsers(this.classEntity.getSponsors()));

...
this.allEventsClasses.add(this.classEntity);
entityManager.persist(this.event);

Hi,

Seems not like the way I would like to see things done. Maybe ask at Seam forum or post full beans code and let us check?

[tony.herstell1]

findEvents(); calls findUsers(); as Seam only seems to run 1 factory.

enter() is where you always enter this method (obvious really as it has @Begin on it)


Notice the "Reattach Users" routine... this is just to deal with the detached users that come back from the RF component.

I do see a lot of exceptions being caught in the server log using that component... conversation problems...

Good luck...
