I can think of one possible case: you have a shopping cart form consisting of a variable number of TextField widgets for the quantity of each item in your form. Each widget requires the Int validator. How would this be handled with stateless forms and widgets ?

Prof of concept in pseudo-python (currently in dev in my box) :
class WidgetCloneComposite(Widget):
def __init__(name, widgetPrototype):
"""
:param name: the name of the widget
:type name: string
:param widgetPrototype: the prototype of widget to clone
:type widgetPrototype: a Widget's instance
"""
pass
def input(self, values):
"""
for each group of values starting with same <name>.<number>.",
create a dict without prefix
call widgetPrototype.input(subValues)
aggreate result with existing.
return aggregated result
"""
pass
def insert(value, input_values,...):
"""
create a list with clones of widgetPrototype :
* renamed with a prefix <name>.<number>.
* call insert on every clone with value extracted (see input())
"""
pass
def retreive_css():
return widgetPrototype.retreive_css()
def retreive_javascript():
return widgetPrototype.retreive_javascript()
Next you could create (if you need) a Decorator that modify input() to assemble the item of list in an table, div or
anything else.
It's the solution, I currently implements for my widget library (plubished near)
