My purpose is to
display a list of page (with MyClass object): this point is
working well but ...
I want that the user
select in my select
list: one page OR nothing.
The HTML select element
supports either single selection (exactly one
item selected) or multiple selection (0..*). To
achieve 0..1 you need
to have a special item
"Nothing" with value '' (empty string) and
in
order to add this item to a Page
(actually DatabaseList) property you
have to
write a custom displayer. Another solution may be to create
a
special page with a MyClass object that
represents the "nothing" value
(when selected), but you still need to hack
something in order to have
this option
displayed first.
Do you have an idea, how can I do that?
I
found a issue too: my select list list
all page (with
MyClass object) ... even my Template with MyClass object who
is hidden.
Does it behave
the same with a DatabaseList property? The Page
property is nothing more than a wrapper for the
DatabaseList property.
