Here are two examples:
<logic:iterate id="product" name="products">
<html:multibox property="productsInstalled">
<bean:write name="product" property="id"/>
</html:multibox>
<bean:write name="product" property="name"/><br>
</logic:iterate>
This handles simple checkbox arrays.
---
However, if you want to have rows of data (more then just checkbox's), I
needed to do something 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.app.CustomerContact)customerContact).getContactName() %>"
size=20 maxlength="<%= com.domain.app.CustomerContact.MAXLEN_CONTACTNAME
%>"></td>
<td class="smallFont"><input type='text' name="customerContact[<%= i
%>].contactTitle" value="<%=
((com.domain.app.CustomerContact)customerContact).getContactTitle() %>"
size=30 maxlength="<%= com.domain.app.CustomerContact.MAXLEN_CONTACTTITLE
%>"></td>
<td class="smallFont"><input type='text' name="customerContact[<%= i
%>].contactPhone" value="<%=
((com.domain.app.CustomerContact)customerContact).getContactPhone() %>"
size=20 maxlength="<%= com.domain.app.CustomerContact.MAXLEN_CONTACTPHONE
%>"></td>
<td class="smallFont"><input type='text' name="customerContact[<%= i
%>].contactEmail" value="<%=
((com.domain.app.CustomerContact)customerContact).getContactEmail() %>"
size=20 maxlength="<%= com.domain.app.CustomerContact.MAXLEN_CONTACTEMAIL
%>"></td>
</tr>
<% i++; %>
</logic:iterate>
Not the prettiest, but it works.
