New Post: Optional Image and Page Field on Custom Data Type

It worked! Hurray! :)

I think the folliwing did the trick:

• StoreFieldType Attribute extended with 'IsNullable = true'
• Setting the Guid type to nullable (Guid? / Nullable<Guid>)
  

Thanks a lot for pointing this out! Tried everything except the above.

Perhaps this is something to add to the developer documentation?


Thanks again for your help!

Best regards and happy coding,
Chris
