1) You have to have two properties in your ActionForm:
public Collection getPrices();
and
public Price getPrice(int i);
Note: getPrice() should return valid Price even if the Vector does not
contain it.
it could look something like this:
public Price getPrice(int i) {
while (pricesVector.size() <= i) {
pricesVector.add(new Price());
}
return pricesVector.get(i);
}
2)
your iterate tag could look something like this:
<logic:iterate
name="editPricesForm" property="prices"
id="element" indexId="i"
type="Price">
<tr>
<td><bean:write name="element" property="oldPrice" /></td>
<td><html:text property='<%= "price[" + i + "].newPrice" %>' />
<html:hidden property='<%= "price[" + i + "].productID" %>' />
</td>
</tr>
</logic:iterate>
You have to know, that the Vector will be FILLED (not just updated) when the
form is submitted.
