tree.jsp example in MyFaces
Hi,
I have 2 questions about the tree.jsp example in MyFaces. I appreciate
if anyone can help me out.
* In the tree.jsp example, it has java code in the beginning, where is
the best place for me to move them? I think it is better not to have
java code in my jsp page.
<%
if (pageContext.getAttribute("treeModel", PageContext.SESSION_SCOPE)
== null) {
2. how can I build the tree dynamically? In this example, the tree model
is built up front (in the init code). Is there a way to built the tree
model so that everytime user expand a tree branch, it populate the sub-tree?
Thank you.
Sam

I think the intent was to make a simple example without requiring a
backing bean. Its just for convenience. A real page would use a
backing bean.

I believe this is possible in the tree component you are using. There
is a new tree component that you may want to check out (tree2). It
will be in the next release and is in CVS now. I can help you if you
have questions on that one.
There will be two tree components so you can take your pick on which
one works for you. I will let Oliver and the tree experts answer
questions about tree.
