Hi,
I found some bugs in store.js and model.js file.
When model store remove callback fired,id argument is an event object. But it used like a removed model instance. And id property is not checked by Model.Store.id . So this code:

1. remove : function(id){
2.     if(id.id !== undefined){
3.         id = id.id;
4.     }

changed to :

1. remove: function(ev,id){
2.         var idProp = this.id;
3.         if(id[idProp] !== undefined){
4.             id = id[idProp];
5.         }
6.       ......
   

In model.js file,model serialize property should be extended like convert property. I think add this code after convert extending :

1.              //add missing converters
2.             if ( superClass.convert != this.convert ) {
3.                 this.convert = extend(superClass.convert, this.convert);
4.             }
5.             //add missing serializes
6.             if ( superClass.serialize != this.serialize ) {
7.                 this.serialize = extend(superClass.serialize, this.serialize);
8.             }

or

1.  each(["convert","serialize"],function(i,name){
2.                 if (superClass[name] != self[name] ) {
3.                     self[name] =extend(superClass[name], self[name]);
4.                 }
5.             })

And I don't find any documentation about that. I used it like that in my tile model:

1.          attributes:{
2.             p:'vector'
3.         },
4.         convert:{
5.             vector:function(raw){
6.                 if($.isArray(raw))
7.                     return new $.Vector(raw[0]*LAT,raw[1]*LNG);
8.                 else
9.                     return this.serialize['default'](raw,'vector');
10.             }
11.         },
12.         serialize:{
13.             vector:function(val){
14.                 return [val.left()/LAT,val.top()/LNG];
15.             }
16.         },

Finally when I updated one property of  a model, update function sent to server all properties of a model. Why? Is this bug?
I think this bug (if it is a bug) is related to makeRequest ( line94 )and model serialize functions( line1538-1544 ).

Thanks,
