I have an other solution for you. Use the updateActionListener tag (just available for MyFaces) within the comamandLink tag. With this tag you can set properties.
<t:updateActionListener value="#{node}" property="#{bean.node}" />
In case of a click to a node the updateActionListener is called and set the attribute node in the bean to the value node.
Then use in the commanlink the attribute styleClass as follows:
styleClass="#{node == bean.node ? 'blackbold':'blue'}">
This is very simple and works.
Hopefully this will help.

Hi Daniel,
thank you for your answer. That's probably a better way than using
another bean property to store the selected node in the listener. But
why and when is the tree.getNode() reset? If you set the node
explicitely by tree.setNodeSelected(evt) is this persistent until the
next node is selected?
Thank you again and sorry for the late response,
Kurt
