Passing tree hierarchy to Flex from ColdFusion CFC

[csteinhilber]

Currently running Flex 1.5. Eventually we'll move to 2.0, which may or may not solve this issue... but for now...

I'm trying to create a hierarchy in a ColdFusion CFC to pass into Flex for use as a dataprovider for a (standard) Tree control.

So I produce an array of structs (objects), with or without children. The final node in a branch containing a data object with several attributes. The problem is that when that last node is displayed in the Flex Tree, it has a child element (ie - it's expandable) that contains an undefined object.

I've tried various combinations of using _remoteClass = "Object", but I still get this phantom final node.

As I've worked through this problem, I've gotten my test data down to a pretty bare minimum (hard-coded... just a single node with a child):

<cfscript>
	aryFinalTreeHierarchy = ArrayNew(1);
	
	strNodeDescription["_remoteClass"] = "Object";
	strNodeDescription["label"] = "Node 1";
	strNodeDescription["children"] = ArrayNew(1);
	
	strChildDescription = StructNew();
	strChildDescription["_remoteClass"] = "Object";
	strChildDescription["label"] = "Child 1";

	strChildDescription["data"] = StructNew();
	strChildDescription.data["_remoteClass"] = "Object";
	strChildDescription.data["doctype"] = "File";
	strChildDescription.data["docsku"] = "GSF345";
	
	ArrayAppend(strNodeDescription.children,strChildDescription);
	
	ArrayAppend(aryFinalTreeHierarchy,strNodeDescription);
</cfscript>

and when I set my Flex Tree's dataprovider to this array, I get the following displayed in Flex:

 + Node 1
 --+ Child 1
 ----+ [object Object], 1, , [object Object], null

Anyone know what I might be doing wrong? Or what I need to do to get rid of that last node?


Thanks in advance,
