I am guessing this is ridiculously simple but I am new to webobjects
and am having a terrible time trying to figure out where various
things link together.
I have a web application with two popup buttons. The first one shows
a list of bus routes. The second one shows a list of stops along
that route. I would like the set list of items in the second button
to reflect the selection of route in the first button. So when the
user selects a route from the first button, something triggers a
refresh so the selection gets made and assigned to the variable
("route") which I use to provide values for the second list of stops.
If I wrap the WOPopupButton in a WOForm with a submit button which
invokes a do nothing action and returns the same page, everything
works. It seems like there ought to be a way to have the action
invoked simply by selecting from the first popup, however. But I am
at a loss for how to do that.
Any help would be appreciated.
Randall
