A WorkbenchDataEditor allows for manipulation of the subscriber data (for example, pricing) via a caplin.services.messaging.Subscription. Generally for workbenches, this is achieved via a caplin.services.testing.SubscriptionStub, for example:

	var oDataSubscriber = new caplin.services.testing.SubscriptionStub("GBPUSD");
	var oMessageService =
	{
		createSubscriber: function(sSubject)
		{
			return oDataSubscriber;
		}
	};
caplin.core.ServiceRegistry.registerService("caplin.message-service", oMessageService);

var oPriceDataEditor = new caplin.workbench.ui.WorkbenchDataEditor(oDataSubscriber, 2000);
oPriceDataEditor.addFieldsByExample({"Bid":"1.1111", "Ask":"1.1112"});

The WorkbenchDataEditor also supports randomly generated updates of data, which is useful for testing price updates.
