I have two selection forms in one html page (see below), each with two
submit buttons, one to "update" a selected database item, and another
to select the item (i.e. store it in a session database) -- the code
for "multiple submit buttons" in one form was found in a web2py
thread. The first form works fine, but the second form after
submission (select or update) is processed by the action(s) of the
first form... I guess it probably has to do with the same "action"
name used in both forms, but I don't know whether it's related to the
_name, _id or "this.form.<action>.value" aspect, or to a combination
of these... Help appreciated! Thanks.
