It is not possible to request an update to an entire model using a wildcard ("*") as the path in a change request. I believe listeners can support wildcards, but not change requests.

So for example, you can't have the following scenario:

var model =

{ foo: "bar", foofer: "barbar", fu: "bat" }

;
var applier = fluid.makeChangeApplier(model);
var newModelValues =

{ foo: "NewBar", foofer: "NewBarBar", fu: "CATT" }

;
applier.requestChange("*", newModelValues);
