I have gone through CDK documentation, and it is a great way to create Ajax enabled components. I am wondering if I could use CDK to extend Richfaces component.

I am planning to extend Rich tree and add more details for the folder and documents. Tree component only displays the folder/document name. I want to display meta data. Something like MAC finder or Windows explorer where you have folder and details next to it in the same row.

Can I use CDK to extend Tree component. If I cannot use CDK, what is the best way to extend tree component.
