RegistarProperty Nullable Types

I am getting an issue with "LoadProperty" call when inserting a new record.  I looked at some previous posts but i think this is an issue with "Nullable Types"

I get an "Index was outside the bounds of the Array." with an outer error "One or more properties are not registered for this type"

Here is my code (that is blowing up)

LoadProperty(Of Guid?)(UserCreatedIDProperty, sxr.GetValue(Of Guid?)("UserCreatedID"))

Here is my property statement

Protected Shared UserCreatedIDProperty As PropertyInfo(Of Guid?) = RegisterProperty(New PropertyInfo(Of Guid?)("UserCreatedID", "ID of User Who Created Item", Nothing))

Public Overridable ReadOnly Property UserCreatedID() As Guid?

Get

Return GetProperty(Of Guid?)(UserCreatedIDProperty)

End Get

End Property

 

THE ERROR:

?ex

{"One or more properties are not registered for this type"}

System.InvalidOperationException: {"One or more properties are not registered for this type"}

Data: {System.Collections.ListDictionaryInternal}

HelpLink: Nothing

InnerException: {"Index was outside the bounds of the array."}

Did you implement the _dummy trick yet?

Thanks Joe... I thought I read through that post completely but I must not have understood the problem fully until now...

i got it now and since i have over 5 classes in the inhertance chain (outside the CSLA classes) i am going to go in and put the "Dummy Static Variable" in place..

i assume it is going to fix everything... so thank you!
