Re: [dali-dev] implicit @Basic annotation and fetchType
|
Hi Tom,
Looks like a runtime bug to me, at least given my interpretation of the
JPA spec. Your runtime is either assuming the picture attribute is
transient or not honoring the eager fetch type for default basic
mappings. I would think those defaults should apply whether the Basic
annotation exists or not. The runtime also might not be defaulting
byte[] to a basic mapping.

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
