Group - Error?

[bowlingbrad]

We receive this error from time to time (see image below). I am wondering if anyone can expand on the meaning of this error. I want to understand WHY we are having this error. Is it because we may be copying a group from one workset to another accidentally? If so, couldn't Revit suggest that we place all instances of a group on the same workset? I don't know...

Doesn't have anything to do with worksets. You'll get this error when working with groups in a non-workset project too. The factory will need to comment on the technical issues, however refere to this for some tips....

Thanks again, Aaron.
Is this considered a bug? Is it just a matter of learning exactly how to manipulate objects within a group? Do you know of any threads regarding group "Do's 'n Don'ts"?
