    Anyone can give an example to use rich:tree in RF 4.0?

    hoveran

      I am trying to use rich:tree in RichFaces 4.0, but existing examples are for 3.3, some classes like TreeNodeImpl is already deleted in 4.0, anyone can give an example on how to write the bean class for rich:tree in RF4.0?

       

      Thanks a lot!

          Hi Hoveran,

           

          You can take a look here for now : http://anonsvn.jboss.org/repos/richfaces/trunk/examples/richfaces-showcase/src/main/webapp/richfaces/

           

          To see it in action you can build the showcase example and deploy to a local server.  Tree is not fully documented yet in our component guide ( but is planned ).

            Hi Jay,

             

            I visit the link, and find the using of rich:tree, but I can't find the codes in RF 4.0 to implement following Bean:

             

            treeBean.rootNodes

             

            Where can I find the codes of TreeBean for 4.0?

             

            Thanks again,

            Hoveran

              Hi Jay,

               

              I can't find org.richfaces.event.TreeSelectionChangeEvent in my using JAR, any place I can find one to take it?

               

              Thanks,

                I found org.richfaces.event.TreeSelectionEvent; in M4. May be it was renamed in M5 because if you look at this link:

                http://anonsvn.jboss.org/repos/richfaces/trunk/ui/iteration/api/src/main/java/org/richfaces/event/ you can't find there TreeSelectionEvent but only TreeSelectionChangeEvent.

                  Thanks for reply!

                   

                  I am trying the richfaces*-4.0.0.20101110-M4.jar, there is no TreeSelectionChangeEvent as example listed. I struggled several days on RichFaces rich:tree in M4, still failed. Not sure anyone has one successful example which can be shared..

                   

                  Thanks,

                    See what I found in M4 show case app(But it seems that M4 app didn't have an implemeted selectionListener so that I'm afraid it may be not working at all in M4 ):
