Hashmap of form command objects

[neonnds]

I have a class to store several command objects:

public class FormCommandMap
{
	private HashMap<String, Object> commandMap;
		
	public FormCommandMap()
	{
		commandMap = new HashMap<String, Object>();
	}

	public void addCommand(String key, Object command)
	{
		commandMap.put(key, command);
	}
	
	public void removeCommand(String key)
	{
		commandMap.remove(key);
	}
	
	public Object getCommand(String key)
	{
		return commandMap.get(key);
	}
	
	public void setCommandMap(HashMap<String, Object> hashMap) 
	{
		commandMap = hashMap;
	}

	public HashMap<String, Object> getCommandMap()
	{
		return commandMap;
	}
	
} // End CLass: FormCommandMap

I have an annotated form controller:

@RequestMapping(value = "/cms/add/page", method = RequestMethod.GET)
public ModelAndView get()
{
    	FormCommandMap fcm = new FormCommandMap();   	
    	Page targetPage = new Page();
    	PageController targetController = new PageController();
    	PageProperties targetProperties = new PageProperties();
 
       	fcm.addCommand("target_page", targetPage);
       	fcm.addCommand("target_controller", targetController);
       	fcm.addCommand("target_properties", targetProperties);
    	
	ModelMap mmap = new ModelMap();
	mmap.addAttribute("form_command_map", fcm);
		
	return new ModelAndView("cms_add_page", mmap);
}

@RequestMapping(value = "/cms/add/page", method = RequestMethod.POST)
public ModelAndView post(@ModelAttribute("form_command_map") FormCommandMap form_command_map, BindingResult result, SessionStatus status) 
{	
    	Page targetPage = (Page) form_command_map.getCommand("target_page");
    	
    	log.info(targetPage.getIdentifier());
    	log.info(targetPage.getClickable());
    	log.info(targetPage.getParent());
    	
	return new ModelAndView(new RedirectView("/cms/add/page/success", true));
}

And I have my view (cms_add_page.ftl):

<form method="post" enctype="multipart/form-data">
  <table>
    <tr>
     <th>
        Identifier:
      </th>
      <td>
      	[@spring.bind "form_command_map.commandMap['target_page'].identifier"/]
      	<input type="text" name="${spring.status.expression}" value="${spring.status.value}"/> ${spring.status}[@spring.showErrors ", " "fieldError" /]
      </td>
    </tr>    
    <tr>
      <td>
     	<p class="submit"><input type="submit" value="Add Page"/></p>
      </td>
    </tr>
  </table>
  
</form>

The bind status ${spring.status} is:

BindStatus: expression=[commandMap['target_page'].identifier]; value=[];

The log output is:

2010-04-19 10:05:31,706 INFO [com.site.web.cms.form.controller.AddPageForm] - <>
2010-04-19 10:05:31,706 INFO [com.site.web.cms.form.controller.AddPageForm] - <true>
2010-04-19 10:05:31,706 INFO [com.site.web.cms.form.controller.AddPageForm] - <>

The problem is, when i submit the form, the bind 'value' is never bound to the string property 'identity' of the target_page command object (which is stored in the hashmap). How can i make the form field 'commandMap['target_page'].identifier' set the identity property of the Page instance target_page.

Any help is greatly appreciated.

Note: I'm using freemarker as my template language.

A very similar issue is described here:

Ok solution was to remove: enctype="multipart/form-data"
from the form element. All works now. Hope this helps someone.
