2006-12-14 Thread Doug Lowder 
(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.

HTH,
Doug

I missed the syntax problem but, interestingly enough, the app works 
without the mx:Array tag - although I'm not sure why.  Tracy is 
correct, the columns property is an Array so it should contain an  
mx:Array tag when declared in mxml.

2006-12-12 Thread Doug Lowder 
That issue is because pets.xml is generating an Object when there is 
a single item, instead of an Array (which it will do when there ai 
more than one pet defined).  Take a look at 
mx.utils.ArrayUtil.toArray() is the docs for some code that will 
ensure you are always dealing with an Array.

Change the model property referenced by the ArrayCollection source 
to animalList.pet and specify it as an array (an Object is 
returned when there is only a single item), and it should work:

mx:ArrayCollection id=anListAC
source={ [ animalList.pet ] }/
