Indexed properties and DynaValidatorForm

[dave sag]

My JSP page complains that "No getter method for property lostSensitiveDataEntry[0].value" when very clearly in my form bean (whcih extends DynaValidatorForm) I have the method:

public LabelValueBean getLostSensitiveDataEntry(int index) {
List l = (List)get("lostSensitiveData");
return (LabelValueBean)l.get(index);
}

and in my struts-xml file i have specified that "lostSensitiveData" is a List and that list has been populated in my reset method fine.
this is almost the exact same code as in other forms I use, only this time, as there are lots of other properties too, I am using a DynaValidatorForm and not an ActionForm. I have even tried extending DynaValidatorActionForm instead but it made no difference.
What am I missing, or is this a bug in struts?
