<p:tree /> for a project I was working on. At the time, PrimeFaces was just starting the path to 3.0, and I was working with a snapshot. The POC was part of a decision making process on which JSF framework, or combination of frameworks to use.This drag and drop example was part of the the work Optimus Prime and his team created as a potential functionality for the
<p:tree /> component. In the final release, this functionality was removed. I still have high hopes that in PrimeFaces 3.5.+ that it will be added back into the product. It was a cool idea and one that we had hoped to take advantage of in our products.If you need this functionality currently, and don't mind using a 3.0-SNAPSHOT release, you can have a drag and drop
<p:tree />. I published this since it was a good example, and I thought someone might need this specific functionality. Otherwise it is code lost in time.The Mercurial project can be pulled from BitBucket and was developed using NetBeans and Apache Maven.
The code can be found here: primefaces-tree-dragdrop-demo

I have a suspicion that you are not using the primefaces-3.0-SNAPSHOT.
What JDK version and Tomcat version?
jdk 1.6 and jboss7.1.0
i am using primefaces 3.5 and JDK 1.6 and jboss 7.1.0. Need help. Also need to create a tree which takes the dta from the db and add delete and edit the nodes. Please help
This specific example was a proof of concept that does not work with anything above Primefaces 3.0 as noted in my post.
We needed the same thing so we used Richfaces
Hi John,
Thanks for your response.

I am trying to create the above example. Any suggestions from you would be of great help. I have also referred to your other example. I am currently able to create the tree. I want to add and delete nodes and display the tree dynamically. This code works on netbeans but not on eclipse.
Thanks,
Poo
The project will work on Eclipse if you are using Maven. The project is an Apache Maven project so it will work from the command line too.
As far as I can tell, you need to update the TreeModel and add additional nodes. You would need to re-render the tree, or the container that contains the tree.
Thanks. I am working on it. Do let me know if you have a sample.
Thanks,
Poo
