Examples of MultiValueField

org.apache.cocoon.forms.formmodel.MultiValueField

A MultiValueField is mostly the same as a normal {@link Field}, but can hold multiple values. A MultiValueField should have a Datatype which has a SelectionList, because the user will always select the values from a list. A MultiValueField has no concept of "required", you should instead use the ValueCountValidationRule to check how many items the user has selected.

A MultiValueField also has a {@link Datatype} associated with it. Incase of MultiValueFields, this Datatype will always be an array type, thus {@link Datatype#isArrayType()} will always return true, andthis in return has an influence on the kind of validation rules that can be used with the Datatype (see {@link Datatype} description for moreinformation).
