Hi,
you mean you want to remove the child from all buyers, but keep the child?
Then your code should be (last two lines are changed):
Vendor child = this.manager.getReference(Vendor.class, vendorid );
|
| Collection listParents = child.getBuyers();
| Iterator iteratorParents = listParents.iterator();
| while (iteratorParents.hasNext() == true)
| {
| Buyer parentForChild = iteratorParents.next();
| parentForChild.getVendors().remove(child);
| }
|
| //remove ALL buyers from child:
| listParents.removeAll();
|
| //Now SAVE the child:
| this.manager.persist(child);
Hope this helps
Wolfgang
