OK, it would appear that if any node in the tree has a null for the value of
the child property the following error is reported by FreeMarker;
Expression stack.findValue(parameters.childCollectionProperty.toString()) is
undefined on line 24, column 8 in template/ajax/treenode-include.ftl.
The problematic instruction:
----------
==> list stack.findValue(parameters.childCollectionProperty.toString()) as
child [on line 24, column 1 in template/ajax/treenode-include.ftl]
in include "/${parameters.templateDir}/ajax/treenode-include.ftl" [on line
26, column 5 in template/ajax/treenode-include.ftl]
in include "/${parameters.templateDir}/ajax/treenode-include.ftl" [on line
26, column 5 in template/ajax/treenode-include.ftl]
in include "/${parameters.templateDir}/ajax/treenode-include.ftl" [on line
124, column 5 in template/ajax/tree.ftl]
----------
which in turn was causing the problem with Sitemesh I was seeing.
Now here's the question; Are we going to allow users to represent leaf nodes
in the tree by having a null for the child property, or are we going to say
that all nodes must return a valid instance of a java.util.Collection when
the child property is fetched?

Bingo :).
Now I've got to work out why I'm getting the following error in sitemesh;
