Cannot remove Item from BeanItemContainer

Vaadin 6 / 7 / 8 Framework Data Binding
1

Hi all!

I have tree items on a BeanItemContainer, that represents POJOS on my Database.

When I try to remove a specific item (One of the POJOS), the method removeItem returns false, and the item is not removed. No exception is trowed.

The other items removes ok. I cant belive on a thing like that. Its really strange.

Always the same entity.

Heres the code:


User usr = (User) tblExecutoresContainer.getItem(tblExecutores.getValue()).getBean();
tblExecutoresContainer.removeItem(usr);

If someone could help how to debug it. Im using Vaadin 6.5.4.

Many thanks

I suspect the bean you are trying to remove is not the original instance you added, and the equals() and/or hashCode() methods for the bean do not behave correctly.

If this is not the problem, some more details are probably needed, but you could try putting a breakpoint in removeItem() in that case.
