[b]hibernate-annotations-3.1beta6[b]

I have annotated a method to take advantage of the Hibernate Validator.

Code:

    @Column(name = "ValueType", unique = false, nullable = false, insertable = true, updatable = true, length = 20)
    @Length(max=20)
    @NotNull
    public String getValueType()
    {
        return this.valueType;
    }

    public void setValueType(String valueType)
    {
        this.valueType = valueType;
    }

If I set a non-null field to null, and do a save, I get a PropertyValueException instead of an InvalidStateException. The @Length constraint is throwing an InvalidStateException like expected. I removed "nullable = false" from the @Column annotation and still got the PropertyValueException.

Is this behavior correct? I was hoping to only have to catch InvalidStateExceptions for validation errors. I don't really see the point of even having the @NonNull constraint if the PropertyValueException is going to be thrown anyways.

Thanks!

The thing is the Validator check the entities that are going to be inserted/updated for real. Hibernate test the not-null at runtime before starting a insert/update action hence the mismatch.
At the end of the day, your entity is properly tested, but I don't see a good way to workaround this mismatch.
