Hi Guys

I have created a custom property which allows a user to select a number of PageTypes located in a MultiSelect control, I wanted to limit the page types which get shown in this control so decided to use Custom settings, so i can select the page types i would want to show in my property.

The issue i am having is everytime i select the PageTypes via a checkbox and try to save i get the following error : Property Id must be of type System.Guid or EPiServer.Data.Identity

Just as a test I added another TextBox field as well into here to see if i edit only this would my settings save and yes they do save as long as i do not select any page types in the checkbox list.

Has anyone came across this before ?
