Save As of an WTPart with Checked-out CADdocument fails ...

... fails when the CADdocument is checked out by someone else.  :-(

So, in detail, a WTPart has a CADDocument associated 'Contribution Content'.  The CADdocument is checked out by a colleague. When I try to perform a Save As, I get something like this in the logs:

Unexpected failure(s)

com.ptc.windchill.uwgm.common.conflict.UwgmErrorException: wt.util.WTRuntimeException: ATTENTION:  Secured Action. You do not have the necessary authorization for this operation. Contact your administrator if you believe you have received this message in error.

When I try to do the same thing, but the CADdocument not checked out, no problem, but no connection between the CADdocument and the new WTPart.  So we are surprissed by the error.

Regards,  Hugo.
