Re: [s2] Confused about s:tree
In my case, I'm retrieving a specific data object from a persistent store and acting on it. However, the only reason I need the list of child nodes is for the s:tree menu, not in other places where I'll use that object, so I'm retrieving the children separately. Then again, even using this technique, I could always set the childList property on my parent data object before exiting the action, so my question is kind of a moot point. Thanks for your insight :) -Brian On 3/20/07, Dave Newton [EMAIL PROTECTED] wrote: snip That I also don't know, so I wonder why I'm replying to this at all!

Re: [s2] Confused about s:tree
Hey Dave,
That helps a lot, thanks!
Do you know if the childCollectionProperty has to be a Set, or can it be
anything that implements the Collection interface? Also, is there any way
to force childCollectionProperty to look in the action class containing the
rootNode object, or does the set of children *have* to be a property of the
rootNode object?

In my case, rootNode is a Hibernate POJO that has a
set name=children.../ mapping element with each
element being the same type as the rootNode.
So the pseudo-class for rootNode is:
public class MyPojo {
// s:tree.../ nodeIdProperty attribute
@property Long id;
// s:tree.../ nodeTitleProperty attribute
@property String name;
// s:tree.../ childCollectionProperty attribute
@property SetMyPojo children;
}
Does that help?

Re: [s2] Confused about s:tree
Hey Martin,
I was looking at the Action class you quoted as I was writing the original
email in this thread. I saw that the example wanted a Category object for
the tree, but I wasn't sure what that Category class was supposed to look
like.
Thanks, though.

Does this answer your question?

[s2] Confused about s:tree
Hi, list I'm trying to render a list of objects from my action class as a tree menu using the Struts 2 s:tree tag, and I'm not having any luck. I can get the static example from planetstruts to work, but the dynamic example only leaves me scratching my head (Without digging in the source, how am I supposed to figure out what a Category class does?). The documentation for the tree tag ( http://struts.apache.org/2.0.6/docs/tree.html) is even worse. Can anyone point out some examples that include what I need to set up in my action class and how s:tree attributes should correspond to action/model class attributes? Thanks, -Brian
