    richfaces richTree can't get item.type!

    Felix Thomas Newbie

      Hi there,

      i'm new to richfaces and i'm testing the richtree component. I have a problem with nodeFace!!

      I understand that it maps the current Tree Node with the type attribute of the possible treeNode tags. But somehow I cannot access it dynamically. If I type: nodeFace="foo" and <rich:treeNode type="foo"> my tree woks completely fine. But if try nodeFace="{item.type}" or nodeFace="#{item.type}" it does not work (I also tried nodeFace="#{item.class.name}"). My tree builds up fine but then I cant access my action="#{organisationseinheitTreeController.selectOrganisationseinheit}".

      I can tell form the sound of my browser that the link has not been activated. It is dead. When I debug my program, organisationseinheitTreeController.selectOrganisationseinheit is not been entered.

      I read somewhere that item represents a bean form my data model, which is nested in the treeNode. Thats why I build OrganisationseinheitTreeItem (By the way Organisationseinheit is German and stands for unit). I listed my JSF JSP, BackingBean and OrganisationseinheitTreeItem below.

      Whats worng?
