I am just trying to evaluate a similar solution for a new project.
So far we have tried using MyFaces, ajax4jsf and Rico
(http://openrico.org/rico/demos.page);
The approach was:
- use Rico for drag-and-drop (quite easy to use and extend)
- use ajax4jsf to reflect changes to the underlying model without submitting
the whole page
The whole thing worked rather smoothly (at least at first sight).
Let me know if you want more details or sample code.

Subject: Extending Treetable component with drag & drop
Hello,
we have to build a new web application containing a treetable showing
hierarchical relations between organizational units as a tree column and
other data for the organizational units in the other columns of the table
like unit name, address and so on.
This can be accomplished using the treeTable component of tomahawk or the
treeTable component delivered by Trinidad.
But an additional requirement to showing the data is to let the
hierarchical structure of the tree be modified by the user.
Our idea is to let the user drag one of the rows in the table and drop it
onto another row in the table. The dragged row and its child nodes should
be attached as a child node to the row it was dropped on.
These modifications in the tree should be visible on the client side but
should also be reflected in the data model on the server, because the
modifications have to be persisted to the database.
So my questions are:
- Is there already a component available which shows a treetable and has
drag & drop support?
- If we have to extend an existing component, what is easier to extend?
Trinidad Treetable or Tomahawk treetable? If we extend one of the
components it would be our aim to integrate this extension into the
existing component to share this extension with others as an optional
feature which can be controlled by tag attributes.
- Is it a good choice to combine ajax4jsf with Trinidad or tomahawk?
- If we have to realize drag & drop ourselves: Is dojo a good choice for
this? Is it a good idea to integrate it ourselves or should we use
something like jMaki?
- Which version of JSF should we use in an application starting in
development now and releasing the first version containing the drag&drop
treetable end of the year? 1.1 or 1.2?
And last but not least: We want to use facelets as view handler and tomcat
5.5 as servlet container :-)
Thanks for reading this bunch of questions.
Any hints regarding some or all of my questions would be greatly
appreciated!
Regards
Jochen
