Or just call isValid again when the
remoteobject returns.
BTW, sending SQL across from your Flex app
to your remote object is generally considered a bad idea from a security
standpoint. You want to just call a general method on your RO that can build
the SQL for you (preferably using a PreparedStatement or whatever the .Net equivalent
is).
Matt
thanks for your response. I will look at isStructureValid(). I used
it ages ago but the example i tried from the flex
docs wasn't making
any async calls. but i will take a look again.
