Dale,
Thanks for the tips. I've updated the ftl file with a default that works
with a null returned by the child property, so I'll be putting a patch into
JIRA.
Al.

A previous example has a three character solution:
https://issues.apache.org/struts/browse/WW-2383 , for this one it appears
that a single "!" may be sufficient.
Excerpted from
<http://freemarker.org/docs/dgui_template_exp.html#dgui_template_exp_missing_default>:
If the default value is omitted, then it will be empty string and empty
sequence and empty hash at the same time.
Now that I read it again, the single character addition would probably
have been sufficient for the previous bug, too. If we want to be
explicit, I think "![]" will use an empty sequence as the default value
here, but it seems unnecessary (and from the docs I'm still unclear
whether that syntax is valid).
