Hi,
I'm using spring-mongo-data 1.2.1, spring 3.2.2,spring-data-commons 1.5.1, mongo-java-driver 2.10.1.
I have a wierd use case.
I have two entities
AImpl:
and BImpl :
Notice that the b member on AImpl is of type interface that BImpl is implementing.
I have an 'AImpl' record on my mongo instance .
you can creat on by executing:
When I'm quering the db:
from a test, the mongo type mapper, gets in action and everything goes smoothly.
But(!!!) when I'm performing the same query from an init method of one of the beans, it fails with this:
Here is the mongo related beans configuration:
In addition I pushed the entire maven project to GitHub so that you can pull/review the sources.
Thanks in advance.
