Something else to add to the docs ;-)

Hi Andrew,
not sure about this but cocoon behaves the following way for multiple
checkboxes:
- if no checkbox is selected, you get no value, i.e.
cocoon.request.get("delItem") is null.
- if one checkbox is selected, you get a simple value, i.e.
cocoon.request.get("delItem") is for example "5".
- if two or more checkboxes are selected, you get an instance of
java.util.List
Only in the latter case you can use the iterator function. In the first
two cases, items.iterator() will
be undefined. So you should actually do some pre-processing like this
to
have a list in any case:
var items = new java.util.Vector();
if(cocoon.request.get("delItem"))
if(cocoon.request.get("delItem").iterator) // no brackets, this
just
checks if it has an iterator at all
items.addAll(cocoon.request.get("delItem"));
else
items.add(cocoon.request.get("delItem"));
This is a little nasty sometimes, but I guess it can't be implemented
differently in cocoon.
HTH,
