Tree Component -- best way to get at TreeNode

hanafey Dec 12, 2007 2:16 PM

The "var" attribute of "rich:tree" gives easy access to the "data" property of interface "TreeNode".

In many cases it is more useful to get at the TreeNode itself (from which the "data" is easily accessible) in order to use an EL to references data stored in a custom TreeNode implementation. One example is to get at a "nodeFace" property that depends on whether the node is editable or not. Another example is the custome TreeNode is good place to implement a "adviseNodeOpened" method.

Is there a way to get a variable bound to the TreeNode in same way it is easy to get a varialbe bound to "TreeNode.data"?

Hello!

It's not possible to do that directly now. I've created RFC on that: http://jira.jboss.com/jira/browse/RF-1629

Until the fix is in place, is a workaround possible by defining a "binding" for the "rich:tree", and defining a method like:

public TreeNode getTreeNode() { return treeBinding.getTreeNode(); }

The question is will this method return the appropriate TreeNode if the "nodeFace" attribute of "rich:tree" is bound to "#{bean.treeNode.XYZ}"?

Thanks for your help.
