(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:
public Vector
getCustomerContacts()
{
CustomerContact
lastCustomerContact =
(CustomerContact)this.customerContacts.lastElement();
if (!lastCustomerContact.isEmpty())
// is this slot being
used?
this.customerContacts.addElement(new CustomerContact());
// always have one available slot at the end of the
matrix
return this.customerContacts;
}
(2) Do not use the reset() method.
(3) On your JSP, use code like this:
<% int i = 0;
%>
<logic:iterate id="customerContact"
name="adminUpdateProfileForm"
property="customerContacts">
<tr>
<td
class="smallFont"><input type='text' name="customerContact[<%= i
%>].contactName" value="<%=
((com.domain.project.CustomerContact)customerContact).getContactName()
%>"></td>
<td
class="smallFont"><input type='text' name="customerContact[<%= i
%>].contactTitle" value="<%=
((com.domain.project.CustomerContact)customerContact).getContactTitle()
%>"></td>
<td
class="smallFont"><input type='text' name="customerContact[<%= i
%>].contactPhone" value="<%=
((com.domain.project.CustomerContact)customerContact).getContactPhone()
%>"></td>
</tr>
<% i++;
%>
</logic:iterate>
(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.
Hope this help,
Jeff

Subject: Question on the ActionForm
design for dynamic data?
Here is the situation.
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 will be a page with contribution plan information and a list of all
the contributors. The information you can edit on this page is the
percentage of share of each contributor. Validation rules are: share need to
add up to 100 and share figure is an integer between 0 and 100.
Since the number of contributors is unknown in advance, how should I design
the ActionForm?
Thanks a lot,
Joyce
