How to retrieve treenode types

[dmatz05]

Hi,

i have one short question:
is there a possibility to retrieve the names of treenode types, which are defined within a tree component?

Example:

<rich:tree ... nodeFace="#{item.type}">
 <rich:treeNode type="TypeA" ...>
 ...
 </rich:treeNode>
 <rich:treeNode type="TypeB" ...>
 ...
 </rich:treeNode>
 ...
</rich:tree>

so how can I obtain a list with {"TypeA", "TypeB", ...} within a backing bean?


Thanks,
Matthias
