Description

While debugging in the Flex SDK source, I found that Alert and UIComponent request an implementation that doesn't exist from the SystemManager. Alex Harui responded to my query with

"That looks like a bug. It should be IMarshalSystemManager. I think it can
cause problems popping up alerts from some Marshall Plan configs."

which is exactly the problem we're seeing. Note that there are no implementations of mx.managers.IMarshallPlanSystemManager or indeed any references other than these two getImplementation calls, so these requests will definitely always return null.
