Andrei Alecu commented on NH-2615:
----------------------------------
Can't seem to do .Fetch(p=>p.Component.Entity) either, it says the expression is too complex.
With .Fetch(p=>p.Component).ThenFetch(p=>p.Entity), it says that the p.Component join is invalid.
I believe the proper solution to this would be to allow a call like:
.Fetch(p=>p.Component).ThenFetch(p=>p.Entity)
Because otherwise the consumer needs to know specific details about how the mapping is defined, and does not work well in polymorphism situations when several classes inherit the same base but are mapped differently (for example some many use components and some may have many to ones)

----------------------------------
I have submitted a related issue at NH-2705 that contains a test which demonstrates this here bug as well.
I think NH-2615 should also be escalated from trivial to major.

Fabio Maulo updated NH-2615:
----------------------------
Issue Type: Improvement (was: Bug)
Changed to improv. since the Fetch (with join) on a component does not have sense.

Fabio Maulo updated NH-2615:
----------------------------
Issue Type: Bug (was: Improvement)
Related to what we will do with NH-2705, ignoring the "Invalid join", we should allow two possible syntax:
1)s.Query<ItemBase>().Fetch(p => p.SubItem.Details).ToList()
2)s.Query<ItemBase>().Fetch(p => p.SubItem).ThenFetch(p => p.Details).ToList()
1) in practice the same behavior you can already write a HQL
2) if we ignore the "Invalid join" we may allow the concatenation of the property path between Fetch and ThenFetch when the property of Fetch is a component.
between this and the related issue we have 4 or more issues of different type/priority (a nice pot-pourri...btw understandable in this situation).
