Hi Andrew,
When I compare my code with your blog
Currently wht I m doing:
I m using treebean which contanins a rootnode and when user click on any
node I found the selected node and make an db call and add child node to
that node programatically. and there is no role of treeModel in my bean I
have just defined it as a reference variable.
is this reason why my tree is loading slow.
Your approach:
If i will create a lazynode which will extend the TreeNode. and I will use
this lazyNode as refernce variable in the treebean and will override the
loadChildren() method of lazynode ( which will call db and get the list of
the child node and set it). This will solve my problem of slow rerendering
of tree.
I am attaching the my treebean with this code.
One more thing which I want to bring in ur notice is that I m using treeData
instead of treeModel to load the tree. Will this lead to any issue related
to slow rerendering of the tree.
<t:tree2 id="clientTree" value="#{accountTreeBean.treeData}" var="node"
varNodeToggler="t"
clientSideToggle="false">

AccountTreeBean.java
Hope I m not bothering you much!
Thanks
