LookupMulti FieldType

[dabaker6]

I currently create fields using AddFieldAsXmlAsync, and use the FieldType Enum to parse whether the field type is valid for the xml. I've noticed though that the Enum does not contain LookupMulti as a field type.

I've found this out adding Mult='True' when just using lookup as the field type and SharePoint allows the field to be created without error, and even allows values to be entered in the field, but the data is then not persisted.

Is it possible to have LookupMulti added to the FeildType Enum (apologies I don't know if FieldType is used elsewhere and will have an impact).
