It is extremely simple to add AjaxAnywhere. there is a small bit of
JavaScript configuration to write that can be done once for all your
pages (you basically setup which form(s) to use with AJAX and also
tell AA if you want to replace the command button action with AJAX or
not). I use AA 1.1.0.6 for stability reasons (had problems with >= 1.2
on facelets).

The code from source forge has an example WAR that has AA working with a tree2.

I found your blogs very useful.  It looks like I can overwrite the 
getChildrenCount() method of my tree node to get around the problems I have.  I 
never used AJAX.  How complicated is it to plug in AjaxAnywhere?

Many thanks for your help,

Jane

FYI:

I also published this code in the jsf-comp project at:

http://sf.net/projects/jsf-comp

It is under the AjaxAnywhere package:

defeated half of the purpose of lazy loading since the sibling nodes actually get 
loaded right away.  So we are actually loading one layer at a time, not one node at a 
time.  To make the matter worse, if a node has no child nodes after the first round, 
the super.getChildren().size() == 0 is always true.  So we repeatly goes to the 
database and try to find more children for those nodes.
