(My last post didn't seem to get through, so I'll try again...)
Flex will interpret the XML as an Object when a single item is
defined, but as an Array when there are multiple items. To ensure
you are always dealing with an Array, you can import
mx.utils.ArrayUtil and use the static function ArrayUtil.toArray()
like so:
<mx:ArrayCollection id="anListAC"
source="{ ArrayUtil.toArray( animalList.pet } }"/>
Search the docs for ArrayUtil.toArray() for some examples.
