Hi Dominik,
I am glad that you found a solution. There is an alternative. You
could annotate your class with something like
@FetchGroup(name="detach_image", member...@persistent
(name="image_data")})
and then you could use
tx.begin();
pm.getFetchPlan().addGroup("detach_image");
Query q = pm.newQuery(...
...
That way they are fetched only when you need them.
