Hi Yury,
Well, you bring up two proposed features for SF here: a standard "values
from query" parameter (which you submitted a patch for), and the ability to
include variables, representing the current content of some other form
field, in the field tag - which could go into a "values from query"
parameter, but it wouldn't necessarily have to. I'll just focus on the
second one here.
This is a complex need, and one that I think is out of the ordinary: you
want users to select a genus, and a color, and then only flowers that match
those two fields, and additionally have an owner specified for them, will
show up in a listbox.
My main question is, what sort of page is this form meant to edit? Is it a
page about a collection of flowers that all share one genus and color? I
don't know if this an actual form you're talking about, or just a metaphor
for a form that holds more technical data that's harder to explain, but in
either case it seems odd. Basically you're talking about creating a subset
of a subset - a group of pages that match both solid criteria (the color
and the genus) and arbitrary criteria (the user's choice). I haven't heard
of that kind of use case - but maybe it makes sense for the circumstances.
Could you explain the data structure of this form in more detail?
