[eclipselink-users] EntityManager.copy/fetch and embeddables

[sr_dd <roe@xxxxxxxxxxxxxxxxx>]

Hi,

i use EL 2.3.2 and work with large object-trees. In order to specify the
fetched object-tree before serialization (especially to reduce it) and
sending to an client i use the copy functionality with AttributeGroups.

First problem i had: 
In some cases em.copy(List,AttributeGroup) throws several exceptions
resulting out of unloaded fields, i think if the same object occurs more
then once in the object tree. I work around this by first executing
em.load(List,AttributeGroup) and afterwards using copy.

Second Problem:
em.copy does not set embeddables. The fields are empty even when i specified
them in the CopyGroup.

Has anybody an idea about that?

regards
Stefan
