List data binding

[Tobia]

Hello
I got this error during spring controller binding:

    org.springframework.beans.InvalidPropertyException: Invalid property 'ingressi[0][id]' of bean class [com.cinebot.bean.json.Ordine]: Property referenced in indexed property path 'ingressi[0][id]' is neither an array nor a List nor a Map; returned value was [1]

this is the Ordine class

    public class Ordine {
    	private List<Ingresso> ingressi=new ArrayList<Ingresso>();
    	private Short puntoVendita;
    	private Integer spettacolo;
    	private Integer[] posti;
    //... getters and setters
    }

and Ingresso class

    public class Ingresso {
    	private String tipo;
    	private Short num;
    	private Integer id;
    	private Integer set;
    //...getters and setters
    }

and this is what is sended as POST variables:

    ingressi[0][id]	1
    ingressi[0][num]	1
    ingressi[0][set]	1
    ingressi[0][tipo]	ingresso
    puntoVendita	1
    spettacolo	24

I can not understand why this is not working. Have you got some suggestions?
Thnak you

How are you binding? What is being posted is expecting a map as a result, so it appears that your binding is simply wrong (post your jsp). It should send something like ingressi[0].id...

This post is send by jquery as ajax request of a json object...
I solved sending raw json instead of form url encoded.
