I've spent the better part of the last two days searching the forums and trying to get a working ListboxField (with multiple values). I originally wanted the Listbox populated with values from a Dataobject, but I'll take anything. I have a working CheckboxsetField, but the users think it takes up too much screen space. I thought ListboxField would be the solution, but I can't get it to work. If it does manage to store anything, it stores "Array".

Thanks,
Brian

Thanks for the help! That example will work with 1 value. Anytime I try to modify it to accept multiple values it stores "Array" instead of the values (even if I pick only 1)

$fields->addFieldToTab('Root.Main', new ListboxField($name = "App2", $title = "App2t", $source = array(
         "1" => "one",
         "2" => "two",
         "3" => "three"
         ), $value =1,$size = 4,$multiple= true));
