Can you confirm at which point your array isn't being returned as
expected ? Go into gateway-config.xml and turn on debug; that'll
let you see what comes over the wire in your console ... so you
can confirm your array comes back over the wire.
In your delegate, trace/assert that the array is not null, and
that it has the number of items you expect.
Then do the same in your onResult() on the command, check it's
not null.
Also (for sanity check) trace that getInboxViewHelper isn't null
either (doesn't look like it should be, but AS2.0 can be too
forgiving ... check everything and check it again !).
I'd also check event.result in the same way in your onResult.
A great "cut and paste" check is just do the following:
public function alertDebug( elements : Array )
{
var debug:String
for( var e in elements )
{
debug += e + ":" + elements[e] +", ";
}
mx.core.Application.alert("debug: " + debug );
}
Use that to alertDebug( event.result ), etc, in your code.
While you're feeling your way around, that should give you
some insight into what's going on between your commands/delegate/
etc.
You could also work backwards; in your ViewHelper, just put
some known static data into the datagrid. If that works, then
change your ViewHelper back, but have your command onResult
send some known static data to the ViewHelper, then work back
to the delegate, etc.
Bottom line ... no obvious gotchas from what I can see, so
roll your sleeves up and learn the joys of Flex debugging :)
Let us know what you find,
Steven
