The target attribute would acclomplish that too. I'm not sure if commandLink
has it but it should.

Thanks Rob...
Using outputLink I got my things working here...
Now I am able to open the document in the right frame when I click on tree
node.
One more thing I would like to ask is,
I am using "commandLink" in some type of nodes in my tree. Now what I want
to have is whenever such type of node is clicked I want to have an action
event fire and also I want to refresh the right frame with some new data.
So is it possible?
Mihir

Have you tried using a plain old outputLink that targets the frame? I've
been thinking about trying to just use the tree in a struts app and if I
could put it in a frame and link to my jsp from it I'd probably save alot
of time.

Sean / Enrique
Actually in my case I have two html frames. In left frame I have a tree and
I right side frame I need to open the selected document (from tree).
Now my only concern is how to call a servlet when I click on document type
node
and hence I can open the document in right frame (I know the code of
streaming the document content).
If possible please guide me with some code snippest...
Below is my code snippet of JSF
<f:facet name="folder">
<h:panelGroup>
<h:commandLink immediate="true" style="text-decoration:
none;" action="#{t.toggleExpanded}"
actionListener="#{CabinetTree.processAction}">
<h:graphicImage value="/images/blue-folder-open.gif"
align="middle" rendered="#{t.nodeExpanded}"
border="0"/>
<h:graphicImage
value="/images/blue-folder-closed.gif"
align="middle" rendered="#{!t.nodeExpanded}"
border="0"/>
<h:outputText value="#{node.description}"
styleClass="nodeTree"/>
<h:outputText value=" (#{node.childCount})"
styleClass="childCount" rendered="#{!empty
node.children}"/>
</h:commandLink>
</h:panelGroup>
</f:facet>
<f:facet name="document">
<h:panelGroup>
<h:commandLink immediate="true" style="text-decoration:
none;" target="contents" action="test.jsp">
<h:graphicImage value="/images/document.gif"
align="middle" border="0"/>
<h:outputText value="#{node.description}"
styleClass="nodeTree"/>
</h:commandLink>
</h:panelGroup>
</f:facet>

You can also have a param whose value is the node identifier. That
is one of the uses I had envisioned for the identifier property (use
the documnet number as the node identifier.) Then just have your
command link point you to the servlet.
I think this is one of the cool parts of tree2. It is very
open-ended. You just use the standard approaches that work in other
situations. So there is nothing special about tree2 that you need to
know here. Take the same approach that you would with h:dataTable.
