I thought this might be of interest to seam-dev mailing list.

Cody are you aware of this issue?

David Lloyd updated AS7-1375:
-----------------------------

   Fix Version/s: 7.0.1.Final
      Complexity: Low


Okay so at best we're looking at changing a module definition, at worst we need to patch one or two EE APIs.  But either way it should be a small change so let's try to get it in for 7.0.1 if we can!
