Hi,
I solved this by overriding formBackingObject like so:
protected Object formBackingObject(HttpServletRequest request)
throws Exception
{
log.debug("entering formBackingObject method");
ToyProvider o = new ToyProvider();
// Find out how many toys we have
Enumeration enu = request.getParameterNames();
int toysManufacturedCount = 0;
while (enu.hasMoreElements())
{
String paramName = (String) enu.nextElement();
log.debug("got request param: " + paramName);
if
(paramName.matches("toysManufactured\\[\\d\\]\\.name"))
{
log.debug("found a toy manufactured");
toysManufacturedCount++;
}
}
for (int i = 0; i < toysManufacturedCount; i++)
{
Toy toy = new Toy();
o.addToyManufactured(toy);
log.debug("added toy manufactured to toy provider");
}
return o;
}
Thanks!
Greg
