Corelib and JSON woes

Question

I would like to serialize the data contained in an
ArrayCollection using JSON. Unfortunately, I keep getting a stack
overflow error when I try and JSON.encode() an array. I tried using
the ArrayCollection.toArray() and I tried just creating a simple
array of objects. I can't seem to get it to work.
If I do this: JSON.encode({prop1:"hello", prop2:"hello"}); it
works just fine.
What am I doing wrong? Anyone know?
BTW, I'm not entirely sure I linked the library up correctly.
I couldn't find any great examples. What I did was add
<path-element>../corelib/bin</path-element> to my
flex-config.xml file and added import
com.adobe.serialization.json.JSON; to my script.
PS. I don't have Flex Builder. I'm using the command line
compiler.

It turns out that it was a problem with my array. I was
looping through an XMLList to build the array.
Here is how I was building it, inside of the result event for
an HTTPService:
var xmlList:XMLList = event.result.caption;
for each ( var xml:XML in xmlList ) {
myArrayCollection.addItem({id:xml.@id, text:xml.text,
time:xml.time})
The JSON encoder was choking on the object's property types
(I'm not sure what they are, I didn't look. Maybe XML text nodes?).
By type casting the xml values, everything works fine:
var xmlList:XMLList = event.result.caption;
for each ( var xml:XML in xmlList ) {
myArrayCollection.addItem({id:String(xml.@id),
text:String(xml.text), time:String(xml.time)})
Thanks for the compiler argument. That is more flexible than
editing the configuration file.
