It seems that your DTMLMethod performs a catalog query (this
returns a "LazyMap" instance) and tries to access
the "threadMessageCount" attribute on it.

Of course, this will not work.
Almost surely, you need to access a single hit (this is a BrainObject),
then call its method "getObject" (to get the true object) and
only then access "threadMessageCount".
