Hi Sri,
You got it right.
This is the code from my Action class that checks for the changes and
forwards the request to the same page again(I tried to forward to a
view-only page(showorderdetails.jsp) for testing purposes and the
changes still were not reflected).
UpdateOrdersAction.java
-------------------------
UpdateOrderForm updateOrderForm = (UpdateOrderForm) form;
if ("updateOrder".equalsIgnoreCase(action))
{
List parametersList = updateOrderForm.getParameterList();
int size = parametersList.size();
for (int i = 0; i < size; i++)
{
OrderDetailModel model = ((UpdateOrderForm) form).getOrderDetail(i);
logger.debug("Form model is: " + model);
}
Iterator iter = parametersList.iterator();
if (logger.isDebugEnabled())
{
while (iter.hasNext())
{
OrderDetailModel orderDetail = (OrderDetailModel)iter.next();
logger.debug(orderDetail.toString());
}
}
logger.debug(" Forwarding to 'edit' page");
NDC.pop();
return (mapping.findForward("edit"));
// this will take you back to the same page
}
Here is an excerpt from "updateorder.jsp":
-----------------------------------------
<html:form action="updateOrder" name="updateOrderForm"
type="mypackage.UpdateOrderForm" scope="session">
<html:hidden property="action" value="updateOrder" />
<logic:iterate id="parameter" name="updateOrderForm"
property="parameterList">
<tr>
<td><bean:write name="parameter" property="orderLineNumber" /></td>
<td><bean:write name="parameter" property="itemName" /></td>
<td><bean:write name="parameter" property="quantityOrdered" /></td>
<td><html:text name="parameter" property="quantityCancelled"
indexed="true" size="3" maxlength="3"/></td>
<td><html:text name="parameter" property="status" indexed="true"
size="3" maxlength="3"/></td>
</tr>
</logic:iterate>
<html:submit/>
</html:form>
I appreciate your help.
