Issue when mediating Object event properties

[Andrew Westberg]

In my mediator, I'm trying to pass along a property that's type
Object. Inside the mediator, instead of the raw Object, I get a copy
of the event itself. Any idea what's going on?

[Mediate(event="WorkstationStatusEvent.WORKSTATION_STATUS_UPDATED",
property="workstationInfo")]
public function handleWorkstationStatusUpdates
(workstationInfo:Object):void
{
//in here, workstationInfo is of type WorkstationStatusEvent instead
of the workstationInfo Object property ON the event
}

First, I would remove the property from the metadata and add a breakpoint at the top of the event handler to confirm that the property is there and is what you expect it to be at the time the handler is invoked. You can also try removing the mediator metadata and adding an explicit event listener on the Swiz central dispatcher for this event, and then debug in the handler to check it that way as well.

How about if you change property to properties?
[Mediate(event="eventName", properties="propertiesName")]

It matters when I switch it in my application.

doh!

I guess it's a bit confusing when on [Autowire] you have "property", but on [Mediate] you have "properties".  Maybe [Mediate] should look for "property" if "properties" doesn't exist.

Well, property on Autowire is to inject a single property. Properties on Mediate is to supply any number of event properties to the handler method. So while it means you do have to be careful, they both are named about the only way they can be. Adding another possible value to Mediate that is almost exactly the same as the existing one ("properties") wouldn't be a good idea and opens up all sorts of fun issues. What happens if both "property" and "properties" are defined being the first one that leaps out.

How about logging warnings for unrecognized metadata properties?
