Doing foreach($treeNode in $DefaultMutableTreeNode.children)

["Pugh, Eric" <EP...@MuseumCompany.com>]

Hi,

I am using the Swing TreeModel to store a tree structure.  I would like to
output it using velocity.  Each of my nodes is a DefaultMutableTreeNode.  

I want to do foreach($treeNode in DefaultMutableTreeNode.children), however
this seems to never enter..  

Can you do a foreach on something that returns an Enumeration?  Or does it
have to be a Vector/Hashtable/ or Array only?

Thanks,
Eric

For the public record, yes, you can do an Enumeration...
