Please try setting the resultFormat to object and the
DataGrid dataProvider to event.result. Also try adding
DataGridColumn and set the dataField to languageId. Please find
more details at the URL below.
If that works for you, great. But i am gong to suggest a bit
more difficult route.
1) Stay with resultFormat="e4x". the e4x API is much more
powerful than the Object API
2) Do not bind directly to a data service call. Instead us a
result handler. This will make debugging much easier.
3) in the handler, trace the event.result as XML to
XMLString() to verify you have what you expect.
4) Watch ut for namespace issues. SOAP is bad about that.
looks like you have an "S" to deal with.
5) build the dataProvider XMLList one step at a time, tracing
ans you go.
