Compound property model

["Mathias P.W Nilsson" <ma...@snyltarna.se>]

Hi,


When testing this the user in the onSubmit is null. I load a list of
Connectors and make an CompoundPropertyModel for the list. Every connector
has a user. How can I achive this so that the list is populated with users
in the onSubmit()?

package se.sosalarm.planner.web.page.chain.connector;

public class ConfigureWindow extends WebPage {

    private static final long serialVersionUID = 1L;

    @SpringBean( name = "connectorService" )
    private ConnectorService connectorService;

    @SpringBean( name = "userService" )
    private UserService userService;
   



	public UserService getUserService() {
		return userService;
	}


	public ConnectorService getConnectorService() {
		return connectorService;
	}


	public void setConnectorService(ConnectorService connectorService) {
		this.connectorService = connectorService;
	}


	private Connector connector;


    public ConfigureWindow(final IModel<Connector> model) {
        this.connector = model.getObject();
        
        IModel imo = new LoadableDetachableModel(){

			@Override
			protected Object load() {
			 return  getConnectorService().getChilds(connector);
			}
        	
        };
        
       Form configureForm = new Form( "configureForm" );
       
       final ListView view = new ListView( "userView" ,  new
CompoundPropertyModel( imo ) ){

		@Override
		protected void populateItem(final ListItem item) {
			
			item.setModel(new CompoundPropertyModel(item.getModel().getObject()));
			final Connector c = (Connector) item.getModelObject();
			IModel ju = new LoadableDetachableModel(){

				@Override
				protected Object load() {
					return getUserService().getAvailableUsers( c );
				}
				
			};
			
			
			DropDownChoice userChoice = new DropDownChoice( "user", 
item.getModel(),ju  );
			item.add( userChoice );
			item.add( new Label( "name" ));
		}
    	   
       };
       
       AjaxSubmitLink submit = new AjaxSubmitLink( "submit" , configureForm 
){

		@Override
		protected void onSubmit(AjaxRequestTarget target, Form<?> form) {
			List<Connector> connectors = (List<Connector>)view.getModelObject();
			System.out.println( view.getModelObject() );
			
			for( Connector c : connectors ){
				if( c.getUser() != null ){
					System.out.println( c.getName() + ":" + c.getUser().getFullName() );
				}
				
			}
			
		}
    	   
       };
       configureForm.add( submit );
       configureForm.add( view );
       add( configureForm );

    }

   
}
