To directly answer your question, no, synchronous data calls are not possible.

Need to verify edit inside of Edit Event.. Quick question, I'm trying to devise a table-edit view of a set of database tables, and am successfully pulling records using e4x etc. At the cell-edition stage, I'm capturing an "itemEditEnd" event on my DataGrid, and that's going well also. My question however, surrounds actual edition, and the cancellation of an edit event. The code should look like this: private function editHandler( e:DataGRidEvent ):void{ if( e.reason == DataGridEventReason.CANCELLED ) return; // get the new input var newData:String = TextInput( e.currentTarget.itemEditorInstance).text; // request the edit ?? if( "edit was bad" ){ e.preventDefault(); // TextInput( dataGrid.itemEditorInstance ).errorString = "Invalid input"; } } "Requesting the edit" above, involves using HTTPService to send the edit request to the server, which will respond with OK, or NOT OK. How can I "wait" for an HTTPService request inside of that function, so that I can call e.preventDefault() if required? AFAIK, the HTTPService only works with a callback-type model? Can I synchronize and wait on a lock like in Java in this case? Much appreciated. Alex
