The default validator for a reference field is IS_EMPTY_OR(IS_IN_DB(...)).
When SQLFORM encounters a field without an explicit "widget" specified but
with an IS_IN_SET or IS_IN_DB validator, it automatically generates a
select widget with options derived from the validator.
In your case, you have replaced the default validator with your own, so you
no longer get the default select widget.
Instead, try just use an IS_IN_DB() validator, which will require the
selection of a value.
