 Description   

This occured in POC demo.

How to reproduce:
1) run any demo that renders flows to switch (create policy, register endpoints).
2) kill ODL, don't remove persistent data
3) start ODL
4) register endpoints again (they were removed b/c OPER DS is not persistent)
5) To see the problem, change table offset.
http://controllerIp:port/restconf/config/ofoverlay:of-overlay-config
{
"of-overlay-config":

{ "gbp-ofoverlay-table-offset": 5 }

}

The problem is that table IDs don't change b/c switches are in PREPARING (not READY as they should be) state.

It's because onDataChanged event in OFOverlayNodeListener haven't occurred and so update method in SwitchManager haven't been called.

I've been talking with Martin about this.

solution could be to implement DataTreeChangeListener instead of DataChangeListener

Tried to replicate this after some time, the problem does not seem to occur anymore.
