field, its name, or id must be provided. When a field is under
nested->nested->iterate->nested->iterate this name is rather complex and there
is no way to read it from the taglib.
So following extensions to html tags would be nice:
- writeNameTo="page/session_attrName" writeNameToScope="page|session"
and when it is set, the calculated 'name' value would be written to the property.
Additionally when such value is needed before the field is rendered, following
tag would be nice:
nested:writeName property="" name="" writeNameTo="page/session_attrName"
