Hi,

I'm using Spring 3.1.1.RELEASE and building a web application. I'm struggling to figure out how I manipulate a java.util.Map (via a JSP) that I want to put in my Model. Here is the method that will serve the JSP page ...

Code:
    @RequestMapping(method = RequestMethod.GET)
    public ModelAndView get(final Model model, final Principal principal) 
    {
		...
		final List<Contract> contracts = m_contractSvc.findContractByOrg(orgId);
		final Map<Contract, Boolean> activeContractsMap = new LinkedHashMap<Contract, Boolean>();
		...
		model.addAttribute("contractsMap", activeContractsMap);
		return new ModelAndView("select");
    }   // getProgramSelect

I would like the Map to be displayed in a series of checkboxes with the label being the key's "name" field. Here's how I plan to process the data ...

Code:
    @RequestMapping(method = RequestMethod.POST)
    public ModelAndView registerForPrograms(@ModelAttribute("contractsMap") final Map<Contract, Boolean> activeContractsMap,
                                            final Principal principal) 
    {
		…
Thanks, - Dave
