Mate How to inject UI component

Question

In the Mate framework for flex. I'm trying to inject a UIComponent into a non UIComponent.

The reason is the UI component is a library component and it has methods that need to be invoked on it. I'm not able to remove the requirement to invoke the methods.

I've got something like this currently

<ObjectBuilder cache="global" generator="{DashboardController}" registerTarget="true"/>
<EventHandlers type="{DashboardEvent.DASHBOARD_CREATION_COMPLETE}">
    <PropertySetter generator="{DashboardController}" 
        targetKey="dashboard"
        source="{lastReturn}"
        sourceKey="target" />
</EventHandlers>

And I'm receiving an error like this.

---------------------------------------------------------
MATE Error: Property type mismatch, turn on the debugger for more information
EventType:test.example.events.creationComplete. Error was found in a EventHandlers list in file DashboardEventMap
---------------------------------------------------------

I've also tried using an object builder to set the property.

Answer 1

I suppose the problem is your lastReturn type isn't compatible with DashboardController.dashboard field. Please recheck it.

Answer 2

Got it working. lastReturn was sometimes returning null even though it was in an eventHandling block.

I didn't realise that the event object was in scope here.

<EventHandlers type="{DashboardEvent.DASHBOARD_CREATION_COMPLETE}" debug="true">
    <PropertySetter generator="{DashboardController}" 
            targetKey="dashboard"
            source="{event.target}" />
</EventHandlers>
