first, i HAVE read chapter 6 & 8

trying to have a collection of classes that implement the same interface, stored in a parent object (one-many)

possible?

i'm using the table per-class hierachy strategy, which seems logical, and works if i try to persist any of the concreate classes individually.. but if i try to save the parent, with a polymorphic collection, it doesn't work.

here's a snipet from the parent mapping file:

<set name="permissions" cascade="all">
<key column="profileid"/>
<one-to-many class="gov.ProfilePermission"/>
</set>

where ProfilePermsision is an interface.

this seems like a pretty common thing to do, but haven't found an example on the forum here, is this not possible?

thanks

"Does not work" is not a particulary helpful description.
