Contrib:tree render problem
Hello!
I hope i'm sending this message to the right place. I've tried to
figure out how to use contrib:tree in tapestry 4. I've managed to
display a tree, and I can expand the root node, but when I try to
expand the following node the whole tree collapses.
Please help me :)
Best Regards,
Istvan

Don't use that tree, use the one at http://tacos.sourceforge.net.

Fwd: Contrib:tree render problem
Posted by Istvan Zakar <is...@gmail.com>.
Hello!
On the dev list suggested me to ask this question here. Can somebody
help me, how the contrib:tree works? If somebody was able to render a
contrib:tree properly pls tell me what I am doing wrong.

+1 :)
The contrib library seems to be very obsolete (Tree, FormConditional, etc.).
This depends on how 4.1 will support AJAX as a core service. (Some
components in tacos are "copy-pasted" from the framework/contrib library
(like Form, Palette) which may make future synchronization of the
development very difficult!)

Norbi

I tried contrib:tree very long ago. Sorry...
But I have no memory problem with tacos:tree.
In the demo app it creates a huge filesystem tree which works fine in a JVM
with 64M heap. (Tested only with 1 user ;)

You should send your question to the user list, not the development.
Maybe somebody uses contrib:tree and can answer your question...

Use Tacos:Tree instead of Contrib:Tree.
Tacos is more actively maintained and supports AJAX, etc...

Hello!
I hope i'm sending this message to the right place. I've tried to

display a tree, and I can expand the root node, but when I try to
