Hi,
is there a way to get some lazy child objekts into the Constructor of an custom query result object?

SELECT new foo.CustomItem(c.name, c.address) from Customer as c join fetch c.address as a

- Without fetch I get an LazyException when using the item.
- With fetch I get the Exception "query specified join fetching, but the owner of the fetched association was not present..."

So what can i do?
thank u
rené

Unfortunately you can't. There has been a jira open for this issue for quite some time. I can't remember the number, but the last time I checked it didn't look like it would be fixed any time soon.

okay, thank you.

Than there is only the way to read the lazy addresses In the constructor with adr.getId().
Again, the ugly n+1 sql problem... ;-(
