Html Component class for rich:tree

[nirvanbd]

Hi,

   What is the component class (html) representing rich:tree in Richfaces 4.0.0M4. I am trying to use rich:tree for my site navigation. I am able to use the tree but it doesn't remember its state when a different page is rendered (all nodes appear collapsed). So I was thinking to use component binding from JSF page and store tree in session scoped JSF bean.

regards,

Nirvan.

Hi Nirvan,

It's org.richfaces.component.UITree. Also JSF spec. strongly recommends against storing UI components in session-scoped beans; so just bind 'expanded' attribute of tree node to the model and store state of the tree there.

Hi Nick,

          I tried to implement your suggestion, and it worked partly. I have created a boolean variable in my TreeNode class that keeps track of its expanded state. However, I am not able to set that variable because I don't know which event I can use to set that variable. I used following

<rich:treeNode expanded="#{treeMenuBean.nodeExpanded}>     

and here are the javabean methods

public boolean isNodeExpanded(){...}
public void setNodeExpanded{...}

The problem is that isNodeExpanded() is getting called correctly, but setNodeExpanded() is not called. As a result, I am unable to set the boolean variable in my TreeNode class.

regards,

Nirvan

Nirvan,

I've remembered that there was an issue with 'expanded' attribute in M4. It should be fixed in M5, can you please try with the latest 4.0.0-SNAPSHOT?

Nick,

      Since I am using toggleType="client", I don't think it would be possible to use the expanded property for setting the nodes expanded. To support this I tried using toggleType="ajax" and the setter setExpandedNode(boolean expanded) gets correctly called.

      Also, I have outputLink in the nodes that point to different xhtml pages, so the richTree component wont be restored and a new one will be created in the xhtml page identified by the outputLink clicked.

      I seem to be stuck, although I have employed a crude fix (for temporary testing).

      Are the snapshots available as direct download? actually I am not very familiar with the maven

Thanks

Nirvan

Nirvan,

The simplest way is to download showcase and extract RF .jar files from there: http://snapshots.jboss.org/maven2/org/richfaces/examples/richfaces-showcase/4.0.0-SNAPSHOT/.
