Simple question: Is there a simple/correct way to call subcomponent
actions? How can I do that?
Here is an example why I need that. I have the following structure
in one of my components:
<wo:AjaxModalDialog onClose = "$clearState">
<wo:WOSwitchComponent WOComponentName = "$componentName">
</wo:AjaxModalDialog>
I need to clear the state of the component instantiated by
WOSwitchComponent, but I don't know how to call the action within
the 'clearState' method on the current component.
I see it is straightforward to access the component hierarchy in a
bottom-up manner (call a parent action, push and pull values from
parent), but I haven't found a corresponding way to do that top-down.
Maybe I'm over complicating the problem, but I haven't found an
efficient way to do this.
Just a thought, but you might try posting a notification from your
clearState() method in the parent component, using the parent as the
notification object. Then in your switched component you can listen
for that notification from the parent object and handle appropriately.
Obviously, you'd have to handle registration appropriately in the
child component so that you have access to the parent component when
registering for the notification--I'm thinking maybe during awake() or
during appendToResponse(), and then unregistering during sleep()?
Either that, or just register for the notification blindly and check
the notification object before clearing the state.
