hmm, the fact that this requires the data to be in the context, and
won't even try to extract it from the URL is causing me a bit of a
problem.

what i'm trying to do is have one template that shows a list of
objects.  if that template is called with nothing, it simply pulls up
the 10 most recent objects and shows them.  however, if that page is
called with an 'objectTypeID' in the URL, i want only the objects that
match that type to be displayed.  this should all happen on this
template, regardless of what the action/form stuff is, preferably this
page will be linked directly from outside sources.  what i had tried to
do is this:

i considered using an invoke element (which is allowed inside a template
block), but then you seem to have no control over the return value.  and
besides, the invoke element is clearly aimed at achieving a different
end than i'm trying.

i think what work best for me in my specific case, is an enhancement to
the output-variable element.  having the ability to use it very similar
to the action.method would be most desirable, and i think the easiest
way to do this would be to have a 'method' attribute allowed in it.=20
then, either the value=3D"" or the method=3D"" would be required, the
value=3D"" being processed as it does currently (using the template
evaluator from the looks of it), and the method=3D"" gets processed
exactly the same way that action.method is processed.

i suppose this might mean that it might make sense to allow
input-variable elements inside the output-variable block, which seems a
bit strange.

what does everyone think?  is this a very specific case, or would
action.method like functionality in output-variable be useful
anywhere/to anyone else?

cheers,
