Alternative to tree2
Hi all
We had a lot of problems with the tree2 component and we search now for an
alternative. The tree component is the most important component in our
webapplication and therefore this is a big risk in our application.
Following behaviour to we need:
- The possibility to klick on every node and to be able to react
(ActionListener).
- The possibility to show graphics on the right side of the node.
- The possibility to close the whole tree.
- The possibility to open a certain path.
- The possiblity to close the last path if the user opens an other path.
(This means only one path should open at any time and all other paths should
be closed).
- Multiselect should work. (Maybe with checkboxes).
- The created HTML code should be as small as possible.
- If the tree is created the first time we would like to open the first
level.
It would be great if someone has experience with an other tree component and
could help me.
Thanks in advance.

Re: Alternative to tree2
Posted by Andrew Robinson <an...@gmail.com>.
For opening closing, there is a treeState property of the tree model
that stores the expanded/collapsed paths of the tree. These paths are
made up of indexes (not node IDs - be careful on this one, it is not
documented anywhere) that are zero based.
So the tree (assuming A is the root node)
A
B
C
D
E
Would have expanded 0 (A), 0:0 (A, B), and 0:1 (A, D).
The default tree state simple remembers these paths and as it is
rendering, looks at these to determine which are expanded and which
are collapsed.
Hope that helps with 1-4

Re: Alternative to tree2
Posted by Hans Sowa <ha...@gmail.com>.
Hi Sean
I guess I could solve the #5 with checkboxes and an attribute "selected" for
every node so it should not be a problem.
But I don't know how I can solve #1 to #4. I tried but I didn't work. So is
there a example around where I can have a look or a description about this
topic.
Thanks.
best regards

Re: Alternative to tree2
Posted by Sean Schofield <se...@gmail.com>.
Tree2 basically can do everything but #5. With some work I'm sure #5
would be possible although I can't say that I would find it very
useful. You would need a submit button to tell the tree component
that you are done selecting. Otherwise how would the component handle
your selections? Seems awkward.

Re: Alternative to tree2
Posted by Hans Sowa <ha...@gmail.com>.
So, I always get an error-message If I try to send to
users@myfaces.apache.org. This is my last try:
Hi Andrew
Here are the points which I hade/have problems:
1) The possibility to close the whole tree.
2) The possibility to open a certain path.
3) If the tree is created the first time we would like to open the first
level.
4) The possiblity to close the last path if the user opens an other path.
(This means only one path should open at any time and all other paths should
be closed).
5) Multiselect should work. (Maybe with checkboxes).
6) The created HTML code should be as small as possible. (I don't think if
this is really possible but it is not so important for me yet).
The really important thinks for me are 1,2, 3 and 4.
Becuase of 5) I think this should work with checkboxes without any problems
but I had not try it so far.
Because of 6) The created HTML Code is really to much. I saw a .NET Tree
from a colleague and the created code are really small. So it would be great
if the tree2 could make a diet for the future.
So, it would be great if I could help for this items.
Thanks in advance.
best regards Hans

Re: Alternative to tree2
Posted by Andrew Robinson <an...@gmail.com>.
A good thought, but not always very practical. If there are a lot of
visible nodes, and the visible nodes have a lot of children, the
performance would be really bad. With the work Jacob and others are
doing on the Avatar front, an AJAX request to get the nodes could take
milliseconds, so the user wouldn't really notice it.
Perhaps we can make sure that someone could extend the tree and do
this if they want under specific circumstances where they know it
would work.

Re: Alternative to tree2
Posted by Sean Schofield <se...@gmail.com>.
Here's something to think about in your free time. I was thinking
that all nodes one level below all visible closed nodes should be
buffered and made visible instanly via DHTML. Then an AJAX request
goes out and creates a buffer for the nodes below the one you just
opened. It should be as fast as client side toggle that way but
without the overhead of tens of thousands of nodes in your DOM that
never get shown anyways.

Re: Alternative to tree2
Posted by Sean Schofield <se...@gmail.com>.
I'm definitely interested in adding AJAX support to tree2. Perhaps
you would like to help me with it? As a starting point you should
familiarize yourself with the realtively new TreeWalker stuff if you
are not already.
My thinking with the TreeWalker is that it will ultimately be easier
to render a portion of the Tree during AJAX requests b/c you can
specify a start and end point, etc. Let me know how serious you are
about helping and I can make some time for it.

Re: Alternative to tree2
Posted by Andrew Robinson <an...@gmail.com>.
I have used AjaxAnywhere and put a <aa:zoneJSF> tag around the tree.
With the Ajax4Jsf library getting some press, it would be interesting
to see how to make tree2 have AJAX support built in, or to create a
new tree component that extends or is similar to tree2 that would
support AJAX natively.
I have avoided non-JSF AJAX solutions (like DOJO integration?) as I
want the full JSF lifecycle (no hacks) and AjaxAnywhere supports it
(and it looks from the website that Ajax4Jsf does as well - and does
it better).
Who knows, maybe we can scrounge up a team of volunteers to integrate
Ajax4Jsf into some new Tomahawk and/or Sandbox components. Once I get
some of the projects I am working on, on the side, done I may be
interested in looking into this (too bad writing open source code
doesn't pay well - or at all).

Re: Alternative to tree2

We have also used tree2 successfully, with more or less similar requirements
- but only for small trees (<100 nodes)
In the near future we will also need tree for quite large amount of data (>
10 000 nodes).
Andrew, it would be very usefully, if you could share some of your knowledge
of combining the tree2 and Ajax...
Or is there any known plans to add ajax support directly to the MyFaces
tree2 component?

What is the problem(s) with tree2? I have been using it with the
functionality you requested. The only I find myself doing is using
server side nodes most of the time (with AJAX, as I have trees with >
100,000 nodes), and I usually create custom tree models and custom
tree nodes as the "Base" ones don't ever have what I need. Perhaps we
can help you through your tree2 problems?

Hi
you could take a look at http://www.ourfaces.net or
http://www.jamesholmes.com/JavaServerFaces/#software-comp (a list of jsf
comp.)
I'm not sure if there is a tree meeting your requirements ...
maybe this helps...
