Deprecated. since 2.13 you should provide the iterator from getCookie method

Allows to attach a special Iterator to a template. This allows templates to completelly control the way they are instantiated.

Better way for providing an Iterator is to return it from the dataobject.getCookie (TemplateWizard.Iterator.class) call.
