Embedded Fields invalid typeOf in PublishingMapping.cs

[dmandava]

DXA 1.6

Problem
TypeOf is not getting extracted out if we add a typeOf for an embedded schema.
e.g. embeddedTypeOf returns tri:Content,ads:Article instead of tri:Content, ads:Article.

Existing code
PublishingMappings.cs Line 343
ApplicationData appData = embeddedSchema.LoadApplicationData(TypeOfAppDataId);
if (appData != null)
{
embeddedTypeOf += "," + Encoding.Unicode.GetString(appData.Data);
}

Solution
We have to extract typeOf and then add ',' separated values of typeOf.

       ApplicationData appData = embeddedSchema.LoadApplicationData(TypeOfAppDataId);
            if (appData != null)
            {
                string typeOfAppData = ExtractTypeOfAppData(appData);
                if (!string.IsNullOrEmpty(typeOfAppData))
                {
                    embeddedTypeOf += "," + typeOfAppData;
                }
            }
