{nil,“ErrorCode”, “Int32”,REALconsoleOnly, REALstandardGetter,REALnoImplementation, FieldOffset(MPImageFilterData, ErrorCode)},
Using Int32 together with REALstandardGetter is a no go, it will go to the Xojo’s ObjectGetter mechanism and generate hard crash there.
So I am assuming that the REALstandardGetter and REALstandardSetter don’t know “Int32” or “Int64” at all.
