[dali-dev] implicit @Basic annotation and fetchType

[Tom Mutdosch <tommut@xxxxxxxxxxx>]

Hi guys,

This may be a JPA runtime issue, but I thought I'd check with all you 
intelligent folk here first  :)  Is an attribute that has no annotation treated 
as a basic attribute (as if it had an assumed @Basic annotation)?

I thought that was the case, but I have a scenario where an EMP_PHOTO entity has 
a byte array and is generated by Dali such as:
@Lob
private byte[] picture;

I execute a query that returns a list of EMP_PHOTOs, but for each instance, the 
picture attribute is set to null.  I assumed that the default fetch type should 
be EAGER for that attribute.  If I add the @Basic annotation:
@Lob
@Basic
private byte[] picture;

Then all of the picture attributes are filled properly.  Is this behavior 
expected?  I am wondering if this is happening because the fetchType is only 
being honored if the Basic annotation is set.  It confused me because the Dali 
JPA Details view was showing the fetchType as EAGER when I didn't have the 
@Basic annotation, but the behavior wasn't corresponding to that until the 
annotation was explicitly added.  I'm not sure if this is a runtime bug, or just 
how it is meant to work.

Thanks
Tom
