Listener on a very first CheckIn

Hello everyone,

 I've developed a Listener that "listen" for a WorkInProgressServiceEvent.POST_CHECKIN and create a BOM files using some rules.

All works fine except that WorkInProgressServiceEvent/POST_CHECKIN seems not to be trigerred on the very first checkin of a "new/only uploaded" EPMDoc.

I wondered if this is a known issue or there is a workaround.

Thank you
