Tree2: Serverside-Tree rerendering is very slow in with Tiles. Pls
help
Hi Friends,
I am using serverside Tree2 with ajax and tiles.
My tree has 3 level excluding root node.
root
' (Level-1)
-------Group name (Level-2)
'--------------Group number (Level-3)
'......................Accounts
Problem:1
when I click on grpName node it fetches & create the child grpnumber node,
but at the time of re-rendering the tree is not expaneded till
groupnumbers(child nodes), it show (+) image at grpname(parent node). Then
again I need to click on + to view the child.
I want the tree to be expanded till the childs how its possible
programatically?
Problem:2
When I click any of the node(every node click is ajax request), behind the
scene in my tree bean(which is in session) the data fetching logic works
fine and create and append the childnode to the parent to the treebean.
then due to problem 1 i have again click on the + img and if child node are
more then 40 it take around 2minutes to referesh and reload tree. Wht i
found its look like Tile is taking lots of time in commiting the response.
Pls let me know the solution.
I am attaching the JSP file
http://www.nabble.com/file/p11468451/accountTree.jsp accountTree.jsp
thanks ...
Novin

Hi Andrew,
Ya I m already working with rechfaces demo tree. I will stick to Ajax only.
Thanks for all of your response.
You are a nice chap.
Have a great day! will bother you again if i will face any pronlem. :);

The code is proprietary, so I cannot give it to you, but I didn't have
to do much to get it working out of the box. So, the best place to
look is at the rich faces demo on exadel's site for the tree.
http://livedemo.exadel.com/richfaces-demo/
If you don't want to use A4J, the trinidad and IceFaces products may
have similar AJAX enabled trees.

Re: Tree2: Serverside-Tree rerendering is very slow in with Tiles.
Pls help
Posted by Novin <no...@ml.com>.
Hi,
Thanks for such prompt reply.
Andrew even in my case i m not creating tree's all levels upfront.
Onece page is loaded first time I create only the first level and on click
of any node of any level I make DB call create the child nodes and append it
to the parentnode.
So you are suggesting go for richfaces tree in stead of tree2 bcas its
creating lots of html code at time of rerendering.
Andrew if you have all ready implemented richfaces tree then can I have ur
code for reference instead of reinventing the wheel bcas some time a samll
problem take lots of time.
Hope you understand my problem.
Thanking you in davance.

Re: Tree2: Serverside-Tree rerendering is very slow in with Tiles. Pls help
Posted by Andrew Robinson <an...@gmail.com>.
In my approach, I used lazy loading of the model because we didn't
have the nodes up front like you do. Getting the children of each
folder was a database call with a lot of children, so getting the tree
all up front would have been really bad for us.
Slow rendering cannot be fixed if the tree is large without a lot of
work. The slow rendering, I find, is due to a lot of HTML generated by
the tree2 component.
We ended up ditching tree2 for most of our trees and started using
JBoss RichFaces tree with A4J to do the updating. Since it uses AJAX,
it was much more suited for large trees and server-side node
expansion. Only time that performance became a problem was for trees
that were initially expanded.

Re: Tree2: Serverside-Tree rerendering is very slow in with Tiles.
Pls help
Posted by Novin <no...@ml.com>.
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
