Alain,
Been following your suggested method, it's great, and everything works as
advertized, except can't get wsResulthandler to fire once the Webservice data
is received.
Also, how do I send the data from the comboBox change event through to the
getWsData function? I need to know the data from the selected item in the
combobox, as that is a parameter I sent to the webservice to get the data. I
hard coded it a number for now, but it doesn't work because of the first
problem.
Here is a snippet of the code in "Class B"
function getWSdata(lobDbId:Number) {
var getUserListResult:Object = new Object();
getUserListResult = root_mc.generatorWS.GetUserList(1)
//lobDbId);
getUserListResult.onResult = Delegate.create(this,
wsResulthandler);
}
function wsResulthandler(data) {
_level0.traceMsg("WS Result recieved.")
this.dispatchEvent({type:"webServiceResult", newData:data})
}
Did I set that up right?
Thanks,
