Description

In our setup we are using an int column as a column designator (called 'type').
this column is then mapped into an enum (called ProductType).
when creating new objects following stacktrace is created:

there is a simple workaround, invoking setType(ProductType.MEMBERSHIP) on the new object fixes the problem. Yet it will be nice if the underlying cayenne mechanism worked with enums/int columns.
