HQL Editor & Hibernate Criteria Editor - do not get DB updates

items table has 2 rows;
I create query in HQL Editor (the same for Hibernate Criteria Editor):

from mapping.querycache.Item

and get 2 items in the "Hibernate Query Result". After that I use MySQL Query Browser and insert 1 more row into the table - so the table has 3 rows.

I execute the query in HQL Editor one more time - and get the same 2 rows - if I restart eclipse workspace and run the query onece again - I get 3 rows.
