/**
* We are overriding this tag, because Stripes will call this method on doStartTag() method, and
* on doEndInputTag() method, stripes will render all registered field, and on binding, Stripes
* will set all missing fields in the request with null. We dont want this behaviour on the fields
* that we set to read-only. We dont want those fields to be registered in the first place, so
* that Stripes mechanism to set missing fields wont set those fields.
*
* @see
* net.sourceforge.stripes.controller.DefaultActionBeanPropertyBinder#bind(net.sourceforge.stripes.action.ActionBean,
