Hi,
I wonder if someone has any ideas on this...
I've attached the code at the end.
Basically I have two grids, each attached to a data provider. The
first grid shows a list of invoices then when a row is clicked on, a
call to retrieve invoice line items is issued. These items are to be
displayed in the second grid.
However, it doesn't quite work out that way!
The top grid gets populated with invoices, no problem. Then when I
click on one of them, I can see in the network monitor that the call
to Coldfusion is issued correctly and with the parameters I'd expect.
I then get an 'onResult' from the RemoteObject in the network
monitor and I can see that all the expected data has been returned...
But the second grid does NOT get populated with this data AND
the 'onResult' function - getSAPInvoiceItemDataResult() - does not
get called!
It seems everyone is working correctly right up to the point the
data's sent back for the items then it hits a wall!
I've pored over this for a good time now and have run out of ideas
(not that I had too many to begin with!). Have I missed something
obvious ? Anyone have any ideas why it might be behaving this way ?
Any help is gratefully received!
Thanks,
Jamie.
