Subject Re: HELP!!! DoubleSeclect tag with default values
Date Mon, 10 Nov 2008 20:17:04 GMT
Hi Jipu,

Well, if i understood correctly, the second list, "tertiaryoptions" is been
completed with only one city, and there is another cities of course. The
doubleselect tag bind the two lists behind through ValueStack. For this
works correctly, verify the first list, "menu.menuoptions". This is probably
a list of MenuOption. Verify if MenuOption contains a list of
tertiaryoptions, something like this:
public class Menuoption{
...
  List<TertiaryOption> tertiaryoptions;
...
}

This is a way to doubleselect binds this two collections.

Felippe.
