If you have any objects in that resultset which are lazily loaded,
then closing the entity manager before you've looped through the

The recommended approach is to store the userName in all lower case, as an
additional field/column, and then do the toLowerCase on the incoming parameter
user name when you do the query and use that field/column that was stored in
lower case.

Yes. You will be able do queries on List properties using standard equality
and inequality filters. You can read more about how to do queries here:

It's possible to orphan a child object, but only if you delete the parent
entity. The reason is that the parent path information is stored in the key
of the child object:

In fact standards attachments works.
But it's not what I'm trying do do.
I'm need to relay HTML messages with inline images and this is still
not working.
Is it a kind of limitation of GAE or is it supposed to work ?
