Good morning.

I am facing a problem when trying to save any information in the google analytics gadget on a page in Edit mode using episerver 7.5.  I am recieving the following error.  Anyone have an idea on why this would be happening.

The parameters dictionary contains a null entry for parameter 'gadgetId' of non-nullable type 'System.Guid' for method 'System.Web.Mvc.ActionResult SaveGraphsLists(System.Guid)' in 'EPiServer.GoogleAnalytics.Internal.Controllers.GaAnalyticsControllerBase'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters

The stack trace is as follows.

[ArgumentException: The parameters dictionary contains a null entry for parameter 'gadgetId' of non-nullable type 'System.Guid' for method 'System.Web.Mvc.ActionResult SaveGraphsLists(System.Guid)' in 'EPiServer.GoogleAnalytics.Internal.Controllers.GaAnalyticsControllerBase'.
