Binding does not work well when you reach up to a parent component. You
will have better luck passing a reference into the sub-component.
In the main app(Myapp):
MyComponent id=mc1 app={this} .../
And in MyComponent:
public var app:MyApp; //data typing is required!
then:
text={app.someComponent.someProperty}

You can bind to the result from the GetResults function directly,
flex
takes care of generating the binding code for you. (no need to
dispatch
events)
E.g.,
mx:ComboBox
dataProvider={this.parent.Webservice1.GetResults.result}/
Or, if you need to invoke a method with the results
mx:ComboBox
dataProvider={myFunction
(this.parent.Webservice1.GetResults.result)}/
define your operation like:
mx:operation name=GetResults/

I have a component that contains a combobox. The component is

by the parent application. I want to populate the component's
combobox with the result received from the webservice in my parent
application.
How can I listen to the result event of the main webservice?
Currently I have the following setup in my main webservice:
mx:operation name=GetResults result={dispatchEvent
('GetResults');} /
In my component, I am trying to add a listener as follows:
this.parent.Webservice1.GetResults.addEventListener(GetResults,
doSomething)
This DOES NOT work! Please help.
Thanks,
Alex
