Hi everybody,
I was wondering what would be the best way to solve the following
recurring problem:
You want to present a user with a list of options, using a
WOPopUpButton. Typically those options are some kind of EO.
By default, the first time the list is presented, the selected
(ideally the first item on the list) option would a *place holder* to
indicate that no actual option is selected.
Now my question is how best to implement this?
The idea is that the dummy place holder is just be an artifact of the
view.
But the WOPopUpButton iterates over a list of EOs so the dummy option
should somehow be a dummy EO in that list and be handled correctly in
various places (check for the selection, preventing from saving the
dummy EO, etc) which makes it hard to prevent it from polluting my
code beyond the view level.
So I'm curious to know how you guys deal with this "problem"?
Many thanks for any insight.
