I have no objection to add a binding attribute. That could be very useful in handling of the situations not already covered by the tree. You could write an action listener and give it a reference to the tree so you can check the current node id, etc.
Here is a link that might help with CVS patches: http://cocoon.apache.org/2.1/howto/howto-patch.html Let me know if you have trouble with it. There are nightly builds available too so you don't have to use CVS. Consider using the CVS source though (at least for helping with patches) because that is what all of the power users are using. If you still have trouble just send me the modified files (use the most recent nightly) and I can take care of it. sean On Mar 31, 2005 4:32 PM, Jon Travis <[EMAIL PROTECTED]> wrote: > It would also be nice if tree2 supported the 'binding' > attribute like a lot of other components.
