cannot perform operation delete on detached object
Heya.
While working with detached entities from a Stateless session bean that was
using a transactional persistence context, I came across the following error
while calling entityManager.remove(foo):

David showed me how to resolve this. I was calling:
public void remove(Archetype ... archs) {
for(Archetype a : archs) {
entityManager.remove(a);
}
}
But I needed to reattach the detached entity bean. So, I changed it to:
public void remove(Archetype ... archs) {
for(Archetype a : archs) {
entityManager.remove(entityManager.merge(a));
}
}
Problem solved (for posterity). Thanks, David!
