It's been a while since his last response.</p> Kevin, would you be able to post an example for us to see? wonder where Ely is. It’s been a while since his last response.

It accepts and ArrayCollection as a DataProvider and we added drag and drop to the renderer so we can interface with other components. At some point I would love to fit this into some of the existing Flex architectures so that I can use it a little more broadly, but I think that will take a little more learning on my part. I made an attempt at implementing the TreeDataDescriptor as you suggested, but found it a little too much work for what I needed right now.</p> <p>I am having one strange problem though. I have decided to nest this component inside a Panel container, but I am finding that if my dataProvider gets large and thus the node instances extend higher that the height of the component, they display on top of the parent Panel component instead of getting clipped/masked as I would expect from any child container of Panel (clipContent = true by default). I am wondering why these instances are being drawn on top of everything. I looked at the code and it appears the drawing is being done in the _lineSprite (Sprite) which is added as a child to the component. Any insight would help since I would think the desired behavior of most components is to have them cliped by parent containers. Thanks for the help. I would be happy to send you my version of the code although it is not really "production ready" for anyone else except our uses.</p> UPDATE & QUESTION:

Specifically, I would like it to be able to take ArrayCollections of objects (in addition to XML) in the same way a tree collection can take multiple hierarchical data types. I am interested to see how you think it would be best to approach this I would love to just be able to extend the component over riding some methods, however do you think instead I would need to start for scratch rewriting it for those purposes.

If you have a moment, you might want to check out our Derby submission which has a graph layout called hierarchical – similar to random walk.

As of now, I’m trying to find a good place in the code to set a currentNode (string) to the currently selected node, but can not seem to get it working.

Maybe I’m just blind?
