Can't Insert Subassembly with rolledback part.

I have a subassembly that I've made which contains a partthat is in a rollback state. I could assemble the part into theassembly even though the part was in a rollback state. Now I'mtrying to assemble the new assembly into another assembly, but itsays I'm not allowed to because one of the parts in it is in arollback state. This does not sound logical. Is this reallyexpected behavior or is something broken?
