Seam Bean that is responsible from refetching the CurrentDocument in case it is Dirty (Transient modifications not pushed inside the DB).

This can happen if a low level Listener decides to RollBack the transaction.

In this case the DocumentModel won't be saved to the DB, but since the ApplyModelValue JSF phase has run, the DocumentModel will have been modified resulting in a Dirty state inside the Context.

We want to keep this dirty state as long as we stay on the same Tab, but as soon as we navigate somewhere else, we must reset the state.
