I also think the external polling is the simplest and most flexible solution.
Besides that, you will want to correlate the file with the
processinstance/token anyway, so using the tokenid in the filename or have a
correlation table where this is done are two possible solutions.

Okay - more searching led to a 'workaround' using Hibernate's native
CascadeTyp.DELETE_ORPHAN setting. I'm not quite sure why a facility like this

Right, this is a known limitation of using Seam with MyFaces, due to how
MyFaces does server-side state saving (I'm not going to call it an actual *bug*
in MyFaces, but it is suboptimal).
It looks like I have forgotten to document this critical thing! Oooop!
