validations in a form with listView

[tubin gen]

I have a form , this  has a listview  , listview contains a chekbox.Upon
form submit I want atleast one check box to be checked,
In a formvalidator I use form.get(id )  this returns formComponent and
formcomponent has a method getValue()but in case of listView how can I
retrieve the  formComponent and its value?

listItemIterator.next().iterator() ;itemChildrenIterator.hasNext(); ){

you can just add formcomponent to your arraylist in populateitem that will
give you list of formcomponents.
you can then validate them in your custom formvalidator..
