Do you also remove the entity from the datamodel and/or list that is backing
the table?

yes, that's what I wanted to remove. I changed my code like this and it worked
smoothly now:
From the controller bean, removed the code:
| public void removeAnItem(Item anItem){
| entityManager.remove(anItem);
| }
|
In the entity bean ShoppingPlan, added this method:
| public
What happens if you have:
| public void removeAnItem(Item anItem){
| entityManager.remove(entityManager.merge(anItem));
| }
|

I am assuming you have a @ManyToOne realationship in the Entity you are trying
to delete. On the @OneToMany side you most likely have
| @OneToMany(cascade = CascadeType.ALL, .)
|
If you change to
@OneToMany(cascade = {CascadeType.MERGE,CascadeType.REMOVE}, )
It may solve
or em.merge( yourUpdatedEntity ) explicitly
