<input type="text"

Why is struts generating a days[10] when there are only 6 days in my
collection? Better still, why is the days index tied to the
employeeAppointments index?

Subject: Indexed properties
I am getting the nested beans out of my form ok but saving gives no joy.
I am trying to use the "2.1 Hand Cranking lazy List in the ActionForm"
from http://wiki.apache.org/struts/StrutsCatalogLazyList. However, I
never see my log messages from the indexed getter methods for any of the
nested beans.
<nested:form action="saveUnitDayScheduleAction.do">
<nested:iterate id="days" property="days" >
<nested:iterate id="workgroups" property="workgroups">
<nested:iterate id="employeeAppointments"
property="employeeAppointments">
<nested:hidden property="statusCode" indexed="true" />
</nested:iterate>
</nested:iterate>
</nested:iterate>
</nested:form>
The form has a collection of DayOfWeekBeans called days.
Each DOW bean has a collection of WorkgroupBeans called workgroups.
Each WG bean has a collection of EmployeeAppointmentBeans called
employeeAppointments.
To that end the form and each of DOW and WG beans have the following
general construct (in a garish form of C++ template syntax).
public <BEAN_TYPE> get<LIST>(int index) {
while (index >= <list>.size()) {
<list>.add(new <BEAN_TYPE>());
}
return (<BEAN_TYPE>)<list>.get(index);
}
And of course the appropriate
public List get<LIST>(){ return <list>;} and Public void set<LIST>( List
<list> ) { this.<list> = <list>;}
The above JSP leads to this html fragment.
<form name="unitDayScheduleForm" method="post"
action="/labor/saveUnitDayScheduleAction.do">
<input type="hidden"
name="unitDayScheduleForm[0].days[0].workgroups[0].employeeAppointments[
0].statusCode" value="N">
<input type="hidden"
name="unitDayScheduleForm[1].days[0].workgroups[0].employeeAppointments[
1].statusCode" value="N">
<input type="hidden"
name="unitDayScheduleForm[2].days[0].workgroups[0].employeeAppointments[
2].statusCode" value="N">
<input type="hidden"
name="unitDayScheduleForm[3].days[0].workgroups[0].employeeAppointments[
3].statusCode" value="N">
<input type="hidden"
name="unitDayScheduleForm[4].days[0].workgroups[0].employeeAppointments[
4].statusCode" value="N">

name="unitDayScheduleForm[5].days[0].workgroups[0].employeeAppointments[
5].statusCode" value="N">

name="unitDayScheduleForm[6].days[0].workgroups[0].employeeAppointments[
6].statusCode" value="N">
<input type="hidden"
