In my case each table sends two different querie to the db:
- how many items are in the data base
- give me all items
If the result from 1) != the result from 2) the error appears in my case. I just thought it might be the same in your case.
Ok, unfortunately not. I only set the before selected items to the grid.
Just an idea: you are having sub-optimal hashCode and equals methods in your objects instead of a unique ID that doesn’t change
ahh, good idea
hasCode and equals always uses the primary key… should not be the problem
