ImplicitSave does not work with 8.3p_2014-10-30

[brevai]

Hi,
Firefox 32.0.3
with 8.3p-2014_05_24 it is working well

What happens:
1) The form is implicitly saving the data,
2) the data is stored in the database
3) in Firebug console I see:

ReferenceError: iframe is not defined
...DY>SCRIPT>parent.isc.RPCManager.retryOperation(window.name);</SCRIPT></BODY></H...

4) the updated field stays blue
5) after a while I get an 'Operation timeout' warning.

Thanks!
