Dojo this.inherit throws 'Uncaught TypeError: Cannot read property 'callee' of undefined'

To facilitate a JsonRest store with a non-standard url scheme, I am trying to inherit JsonRest and override the _getTarget(id) function. Here is what my inherited javascript class looks like:

define([
    "dojo/_base/declare", 
    "dojo/store/JsonRest",
        ],
function(declare, JsonRest) {
    return declare(JsonRest, {
        _getTarget: function(id){
            var target = this.target;
            if(typeof id != "undefined"){
                if(target.indexOf("{id}") != -1) {
                    //use template
                    target = target.replace("{id}", id);
                } else {
                    target = this.inherited(id);
                }
            }
            return target;
        },
    });
});

However the line target = this.inherited(id); returns an error: Uncaught TypeError: Cannot read property 'callee' of undefined.

I looked at the docs, and I think I am doing it right: http://dojotoolkit.org/reference-guide/1.10/dojo/_base/declare.html#calling-superclass-methods

What is the proper way to call the base class's _getTarget(id) function?

If you look closely the part of the documentation you linked, you are supposed to literally pass the arguments object to this.inherited - that's what contains the callee property it is looking for (and will include the id and any other arguments anyway, to be passed along to the superclass).

A few paragraphs in, the documentation also explains how to call this.inherited with arguments other than the same ones passed, if necessary: you can pass custom arguments in an array after arguments, i.e. this.inherited(arguments, [ ... ]). arguments always has to be first.
