i copied the wrong bits in the previous email, same target but its actually
spark.components.DataGrid (@2ecd2ae1).
rebooting didn't help, except that its now consistently just double events.
watching the backend (sql server & coldfusion servers), i can see nothing is
sent thru until the 2nd GridItemEditorEvent comes round, then 2 remote calls are
done. even sticking in a timer in the event listener top slow things doen
between the events, doesn't effect this, both come thru at the exact same
instance (eg. '2013-11-07 21:29:02' though maybe coldfusion's timer isn't
detailed enough to pick up sub ms differences, still looks same to me).
real head scratcher.
