I believe Observe / Value is what I want to use for a current
challenge, but try as I might, I just cannot seem to wrap my head
around it. Hoping someone could take another kick at the cat to
explain it in context of the following situation:
My component (SWC) is defined inside a view and has a public property
that is databound to my modelLocator for it's XML source. When the
right data conditions are met internally it broadcasts an addressEvent
with all user selected data.
<pcall:pcall id="PointofCall" left="10" top="50"
postcodeXML="{ModelLocator.getInstance().PointOfCall.postcodeXML}"
AddressEvent="AddressEventHandler(event)" />
When the user provides input data, I broadcast a search event and
receive the updated XML from the services / delegator. There is a
public method - currently titled Update() - in the component to parse
the XML and build up it's display accordingly. Within the view I can
bind a button to that Update() function and the parsing goes smooth.
<mx:Button x="333" y="10" label="Button" click="{PointofCall.Update()}"/>
But the problem is that I only know when the data is updated in the
onResult method of my command that sent the data off in the first place.
How do I - in a command - trigger the method of a component on a view?
Thanks,
Jamie
