"invalidReason":"Expected a link (because this object's type is not a value)

[Arturo Ulises Castañeda Estrada]

HI Dan

I have the problem trying to persist in the DB,  i send this

shoppingCart:{href: 
"http://192.168.0.20:8080/restful/objects/simple.ShoppingCart/140"}

but returns the next error:
{"shoppingCart":{"value":"{\"href\":\"http://192.168.0.20:8080/restful/objects/simple.ShoppingCart/140\"}","invalidReason":"Expected
 a link (because this object's type is not a value) but found no 'href'"}

I find the thread where you talk about json-node:

Could you explain me how to use or how can i resolve this, thank's
