I’m getting this error when trying to, create or edit a filterfield. Even with no options added i get this error. It “might” have happend when upgrading to 6.2.3-patch-1812141742 from 6.1, but im not sure on that.

IWebLog exception ‘Validation error for FieldDefinition(SystemId: a6c704ee-3f1f-4de9-8eed-9905ce559c57, Id: AcceleratorFilterFields), Option: ‘Litium.Accelerator.FieldFramework.FilterFieldTypeMetadata+Option, Litium.Accelerator’ behöver implementera Litium.ComponentModel.IReadOnly.’.’: 93b9fed2-1c92-4354-bb8d-5b3b8f6ae752(Option:Litium.Accelerator.FieldFramework.FilterFieldTypeMetadata+Option, Litium.Accelerator’ behöver implementera Litium.ComponentModel.IReadOnly.:wink:

As the error message said, the Option class needs to implement IReadOnly, after you upgraded to the new version, in order to have the cache object immutable. The easiest way is to inherit Litium.ComponentModel.ObjectBase.
