> If the property specified in the childProperty for an s:tree returned a null the following
freemarker error occurs;
> 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]
> ----------
> The attached patch fixes this problem by using a empty list as the default if a null
is returned.
