In Umbraco 7.15.3, I have a MNTP2 storing a list of related members on a member profile. I call the property "memberReferrals".

I am trying to query the value, update it and save using through the memberservice:

Guid referringMemberGuid = new Guid(model.ReferringMemberGuid);
var referringMember = memberService.GetByProviderKey(referringMemberGuid);
var myValues = referringMember.GetValue<IEnumerable<IPublishedContent>>("memberReferrals");

In the case above, myValues returns empty, even though there is an entry in the profile and the property returns not null.

I can do this by using the Umbraco helpers and the values return as expected...but not when using the memberservice.

    Guid referringMemberGuid = new Guid(model.ReferringMemberGuid);
    var referringMemberHelper= Members.GetByProviderKey(referringMemberGuid);

    if (referringMemberHelper.HasValue("memberReferrals"))
    {
        var pastReferrals = referringMemberHelper.GetPropertyValue<IEnumerable<IPublishedContent>>("memberReferrals");
    }

Any ideas why this would you cant get MNTP values returned from MemberService? Seems a little excessive to have to use both the IMember service plus the IPublished content just to get and update a value.
