Duplicate OIDs within the same Database

[muren400]

Hi,

not sure if this is actually a bug or not, but I read somewhere in the wiki, that oids should be unique within a database. Nonetheless I stumbled upon two different IfcProject entries that share the same oid. Is this a very unusual glitch that one should be concerned about or can there be duplicate oids for different revisions?

Thanks, Andreas

PS.: this happened in 1.5.182

Depends on how the two IfcProject entities are "different". If you create revisions by using the low level interface, then yes - you will have one stable oid for an entity throughout different revisions (see Database versioning). In that case, the two IfcProject entities wouldn't actually be "different". Otherwise I think it is rather unexpected.

It's two different IFC Files checked in into two different subprojects.

There were two rollbacks during the checkin of the first model. The Server was restarted twice before the checkin of the second model.
