For the XML problem, it's in a class that the Command class calls. The
constructor load the XML file stored locally, then the completeHandler
calls XML(event.target.data) and assigns the XML to a local variable.
However, when I instantiate this object, then call a method on it, the
XML is still null. If I put a timer on it to stall for a second, it's
there....

A work around is to instantiate the XML on startup so the XML is there
before calling the set on @ID, but means more memory.
