Hi Pritam,
I migrated a few weeks ago to the richfaces tree which has ajax support
on board.
Maybe it's an alternative for you.

Hi Pritam,
I had a similar problem in one of my projects and we solved it by
making the tree AJAX aware - which means that we only loaded the first
section of the tree with the site and then loaded other sections on
demand if a user clicked the related "+".
However, if that is not possible for you, you have 2 other options: 1)
use a different tree component from another library (not tomahawk) or
2) write your own tree component.
I hope this helps!

Hi,
We are using tomahawk's tree2 component in our application. We have more
than 12000 nodes in the navigation tree which is the most important
component of our application.
The problem is- with 12000 nodes tree renderer generates large amount of
html (~ 20MB) which is repetitive and the browser takes almost 40-45
minutes to render the tree. So, do we have any way to avoid this
problem?
Mentioned below html is only a small part of what's being sent from the
server.
