# 831 D6 Build Does not Implement InternalPost Method Correctly Causing Required TFields to Be Ignored

---

I have just noticed that DBISAM doesn't anymore give a "Field XY must have a value" for any Field for which we have set Reuired to True in the fields editor. The problem is that from Delphi 6 on the CheckRequiredFields call was moved to TDataset.InternalPost.
As you do not call the inherited InternalPost, this call is never called. So you must change this for D6.
