Thanks. I moved my call to populate the dropdown values from the Action
descendant perform() method to the ActionForm descendant reset() method.
That worked & makes sense to me.
Question: Is this violating any kind of "separation" rule that I'm going to
get drilled on by other developers?

That's what the reset method of the FormBean is for. The ActionServlet
calls that method before populating request parameters when the bean was
created. (So, if it was in request scope, on every submit - actually, you
have tosave the state of your options in some way and reset it in the
reset method. Or you use a session bean and the reset is called only
once to initialize the bean - but save it's state between submits.)
