    UIOMaticListViewField

    Hi,

    I am trying to create a field that has te be shown at the listView. I am creating this field as following:

    [UIOMaticListViewField, Ignore]
public string MemberName { get { return
MemberRepository.ngetMember(MemberId).ToString(); } }

    This works perfectly at the listView but now, when I want to create a new item is gives the following error (logs are empty):

    Server error: Contact administrator, see log for full details.
Failed to get scaffold

    I can not find any information about this on the internet or in the documentation. Am I missing something?

    Kind regards, Yanick

    Hi Yanick,

    Hmm must say I haven't tried it with a getter that actually does anything :p so you might have hit a bug, will try to reproduce and come back to you.

    The scaffold method basically does the following 

    public object GetScaffold(Type type)
    {
        var obj = Activator.CreateInstance(type);

        var a1 = new ObjectEventArgs(type, obj);
        UIOMaticObjectService.OnScaffoldingObject(a1);

        return a1.Object;
    }

    So don't see immediatly why it would fail

    It is just a simple class with a static method that looks like this:

    public static Models.Member ngetMember(int id)
    {
        var db = ApplicationContext.Current.DatabaseContext.Database;
        return db.Single<Models.Member>(id);
    }

    It's probably because MemberId is still null, so try checking for that before calling the MemberRepository

    Something like

    [UIOMaticListViewField, Ignore]
public string MemberName { 
  get { 
            if(MemberId == null)
                  return string.Empty;

            return MemberRepository.ngetMember(MemberId).ToString(); 
        }
}

    Let me know if that does the trick

    And I assume memberId is an int so the check will be

    if(MemberId == 0) return string.Empty;
