LLBLGen 3.0 Runtime: 3.0.10.1025 SelfServicing, .NET 4.0 SQLServer database

I have some fairly simple code that uses an IncludeFieldList to retrieve only 1 field from the database:

IncludeFieldsList includeFields = new IncludeFieldsList(XFields.Y);

XCollection c = new XCollection();
c.GetMulti(predicate, includeFields, null);

Then, for some of the entities in the collection, I want to fetch all the fields:

XEntity x = c[0];
x.FetchExcludedFields(includeFields);

But, I'm getting Exceptions thrown in two cases:

First, my entity includes a Read-Only field (marked as such in the designer). It's not included in the IncludeFieldList, so I it should be fetched when FetchExcludedFields is called. But, I see this exception:

SD.LLBLGen.Pro.ORMSupportClasses.ORMFieldIsReadonlyException occurred
  Message=The field 'RowVersion' is read-only and can't be changed.

Second, one of the fields in my entity is mapped to an Enum, using the basic enum support in 3.0 (not a custom type converter). This field is not included in the IncludeFieldsList, so it should be fetched when FetchExcludedFields is called. But, I see this exception:

SD.LLBLGen.Pro.ORMSupportClasses.ORMValueTypeMismatchException occurred

Is that one field you are fetching the PK of the entity? If not, please include the PK field in the first fetch routine, and see if this solves anything.

If not, please attach a simple repro better on Northwind.

btw, is that entity being fetched a part of an inheritance hierarchy?

Both should work fine. We'll look into whether we can reproduce them.

Could you test the attached dll please?

The attached dll fixes both issues.

Thanks!
