I was trying to get the same behavior that you describe, and my initial
attempts to use t:selectOneRadio with layout="spread", combined with t:radio
tags in the facets of my t:tree2 nodes failed. When JSF was processing the
t:radio tags, it could not find the selectOneRadio component referred to by
the "for" attribute of the t:radio tag, resulting in a "Caught exception:
IllegalStateException with the message "Could not find component
'job-select' (calling findComponent on component
'tree2-test:job-tree:0:0:0:_id26')" in my browser.

As it turns out, the key was that I needed to be more specific with the
"for" attribute of my t:radio tag; rather than simply referring to the id of
the t:selectOneRadio tag like this:
    <t:radio index="#{node.index}" for="job-select" />
I had to qualify it with the id of the h:form tag that contained
t:selectOneRadio:
    <t:radio index="#{node.index}" for=":tree2-test:job-select" />

"tree2-test" is the id for the h:form that contains the tree and
"job-select" is the id for the t:selectOneRadio tag.

This is similar to that approach recommended in the "Dynamic Example" on 
http://wiki.apache.org/myfaces/Display_Radio_Buttons_In_Columns this MyFaces
wiki page , except the t:radio tags are included in tree facets rather than
table cells.

The end result is that I was able to get the value of the selected radio
button in my backing bean, and use it to process the specific node that the
user had selected in the tree. I'm using Tomahawk 1.1.2 with the Sun's JSF
reference implementation 1.1_01 running on Tomcat 5.5.7.

RE: selectOneRadio in tree2 ?

[Michael Heinen <mh...@recommind.com>]

Thanks Scott,

I use also a t:selectOneRadio with spread layout and added an index
attribute to my nodes.
The value of the for attribute must be full qualified as you said.
This took me some time.
