Web service - Parsing multi object with JSONp

Hi Guys,

I’m having an issue with rest_ws, I am trying to send an object with jQuery JSONp AJAX request, but Servoy converts it to a single array property

e.g.

this is the object i am trying to send

data = {
 	'lines'	:{
				1:{
	    			'product_code'	: '640',
	    			'qty'			: '3',
	    			'price_sales'	: '25',
				},
				2:{
	    			'product_code'	: '641',
	    			'qty'			: '5',
	    			'price_sales'	: '40',
		    	}
	}
};

this is my callback

"lines[1][product_code]" 	: 640
"lines[1][qty]" 			: 3
"lines[1][price_sales]" 	: 25

"lines[2][product_code]" 	: 641
"lines[2][qty]" 			: 5
"lines[2][price_sales]" 	: 40

Is there someone who has find the solution for this problem
