I added the mx:array even though it works (with more than pet in the
file) without it, and it still worked, but I was hoping it would
solve solve the problem I get when there is only one pet in the file.
Before it was just nothing, but since I added Tracy's mx:array it
pops up an error window in the browser that says this..
TypeError: Error #1034: Type Coercion failed: cannot convert
