Hey,
I talked about IRRE Handling with Jochen last week.
There's a difference between what the "tutorial" and the "core-api" 
tells IRRE Users.
Jochen went along the tutorials building the IRRE. But this prooved as 
complicated since there's no real "prediction" possible what the child 
record will be (same configuration, different result).
The current CORE API is a bit more precise there and does not allow 
"dirty configuration" but also enables "typical mm support".
Since the core-api version technically is more precise, and tutorials 
some kind of outdated, we came to the conclusion that in 4.3.x we will 
stick to the current behavoiur and try to fix as much as possible and 
with 4.4 (and so extbase 1.2) introduce the new behavoiur along api.

So in short:
this won't be possible in extbase <= 1.1.x (4.3.x)
for extbase 1.2.0 (>= 4.4.0) IRRE handling will be refactored, then 
foreign_selector will do its jobs in extbase correctly.

You may use "1.2" patches (afaik currently not public). I may provide 
mine, which work for now, but for shure they won't be the exact 1.2 
implementation.
