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?
