Any component can retrieve an application parameter as Application.application.parameter.personid. There is no point in pushing a parameter like this down into every component. It is stored on the Application instance and components should access it there instead of keeping redundant copies of this information.
If you really want to pass it down to SiteList, you can simply declare a public var rather than writing a setter. (BTW, setters without getters are weird.) And if you do write a setter, the convention is to name it personID, not setPersonID (and to name its private storage var _personID).

In partial answer to my own question (and not seem a complete and utter idiot) here's what Im currently doing: In my component (SiteList) I have a setter function: private var personId:String; public function set setPersonId(p:String):void { personId = p; } In my main component: <SiteList width="218" height="378" setPersonId="{personId}"/> Is this the recommended way? What are the alternatives? Thanks again. Kr. Luke. Luke Vanderfluit wrote: > Hi. > > I have a flex application that gets called from an html link and is passed a > parameter.
