Lazy many-to-many properties don't load on demand? (2.1.1)

[Pawel Veselov]

Hi.

I'm using 2.2.1

I have declared a ManyToMany property, with lazy fetch type (my entities
are all property based).
The property does not load when accessed (the collection is null).
Setting it to eager loading works, but I don't want (for performance
reasons) for it to always load.

Is there something I may be missing?

Thank you,
  Pawel.
