Hi!
I'm trying to achieve the following:
I'm having 2 widgets. The first widget, A, should determine whether the
second widget B is displayed either as
- a drop down where a user can choose one of several predefined values
- or: as an input box where a user can enter data freely
Now if I start out with widget B as a nomal input field, then use the
on-value-changed of widget A to add a selection list to B via flowscript
this works perfect. The problem starts if I now try to unset or reset
that selection list so the widget becomes a standard input field again.
From what I can see in the cocoon source resetting or removing a
selection list once it is set does not seem to be possible. Using
setSelectionList(null) will just be discarded and I can't find another
method that would accomplish this. Is there something I oversaw?
I'm not sure about deleting selection list but what about using union
widget[1]? Is there anything that stops you using it? Use of Union
widget should lead to cleaner form definition, also.

Thanks Grzegorz! Actually I was thinking about using Unions. In my case
however this would make things more complicated. One of several reasons
being that the selection list for my A widget gets filled dynamically.
Now the set of possible values for my A widget is pretty much unlimited.
That way I cannot setup union cases in my model as I do not know all
possible values up-front.
Anyone knows if removing a selection list from a widget is possible or
maybe if it's intentional that there's no such possibility?
