Something may be a little funny with the field-metadata tag, or maybe with
the form tag itself; I'm not sure. What I see is that there seems to be some
sort of namespace collision problem between attribute names on my tags and
names somewhere in a relevant contextual domain.  For example, if I create a
custom tag with an attribute called "name", then when I get to the call to
the field-metadata tag in that form there's a NullPointerException thrown
from inside the PropertyExpressionEvaluation class (not clear to me why due
to my general cluelessness about how the code works).  If, however, I alter
my tag in no way other than to change its attribute name to "banana" (also
changing the invocation of my tag in my form, of course), then the page runs
just fine.

I'll attach the stacktrace. I don't think I'm smart enough to be doing
anything exotic on my pages. Maybe the namespace collisions I'm seeing are
part of everyday life with tag file libraries; I've only done a few of
those.
