Hello Ellen,
You are speak about indexed properties. It can be defined by two ways
1. One method for get and set operations
public String[] getSomeProperty() {}
2. Two methods
public String getProperty( int index ) {}
public void setProperty( int index, String value ) {}

EL> (1) Have a Vector / Collection of contributors (ie. getContributors()) belonging
to your form. Inside that function, check to see if you need more rows by using code
similar to the following:
EL> public Vector getCustomerContacts()
EL> {
EL> CustomerContact lastCustomerContact =
(CustomerContact)this.customerContacts.lastElement();
EL> if (!lastCustomerContact.isEmpty())
// is this slot being used?
EL> this.customerContacts.addElement(new CustomerContact()); //
always have one available slot at the end of the matrix
EL> return this.customerContacts;
EL> }
EL> (2) Do not use the reset() method.
EL> (3) On your JSP, use code like this:
EL> <% int i = 0; %>
EL> <logic:iterate id="customerContact" name="adminUpdateProfileForm"
property="customerContacts">
EL> <tr>
EL> <td class="smallFont"><input type='text' name="customerContact[<%= i
%>].contactName" value="<%=
((com.domain.project.CustomerContact)customerContact).getContactName() %>"></td>
EL> <td class="smallFont"><input type='text' name="customerContact[<%= i
%>].contactTitle" value="<%=
((com.domain.project.CustomerContact)customerContact).getContactTitle() %>"></td>
EL> <td class="smallFont"><input type='text' name="customerContact[<%= i
%>].contactPhone" value="<%=
((com.domain.project.CustomerContact)customerContact).getContactPhone() %>"></td>
EL> </tr>
EL> <% i++; %>
EL> </logic:iterate>
EL> (4) Have a button on the form "Add more rows" in which case the form posts to
itself and will cause a new row to be added at the bottom of the grid.
EL> Hope this help,
EL> Jeff

EL> Here is the situation.
EL> I am developing a system to maintain a contribution plan. I need to input the
plan information first and add unlimited number of contributors, specifying each share
of the plan. So there

contributors. The information you can edit on this page is the percentage of share of

Since the number of contributors is unknown in advance, how should I design the
ActionForm?
EL> Thanks a lot,
