Hi,
I have modified the 'its' example in js.c to understand this better.  I have the problem when the JSClass.call hook is invoked for an object, that the global object is passed into the handler, not the object that is being worked upon.  Any ideas for a solution?

Added TestCall method to this example
static JSClass its_class = {
    "It", 0,
    its_addProperty,  its_delProperty,  its_getProperty,  its_setProperty,
    its_enumerate,    its_resolve,      its_convert,      its_finalize,
	NULL, // getObjectOps
	NULL, // checkAccess
	TestCall, // call
	NULL, // construct
	NULL, // xdrObject
	NULL, // hasInstance
};

It("color") method/property doesn't work cause obj is global object.  + can't get private data for this object, you would get private data for global.

static JSBool TestCall(JSContext *cx, JSObject *obj, uintN argc, jsval *argv, jsval *rval)
{
	printf("testcall() object %lu arc %d\n", obj, argc);
    *rval = OBJECT_TO_JSVAL(obj);
    if (argc != 0)
        JS_SetCallReturnValue2(cx, argv[0]);
    return JS_TRUE;
 }


it.item("color") method/property works

static JSBool its_item(JSContext *cx, JSObject *obj, uintN argc, jsval *argv, jsval *rval)
{
	printf("item() object %lu %d\n",obj,argc);
    *rval = OBJECT_TO_JSVAL(obj);
    if (argc != 0)
        JS_SetCallReturnValue2(cx, argv[0]);
    return JS_TRUE;
}
