Is anyone out there using Solidworks and Windchill?  I've posted this on the PTC Community support site as well. 

At my company, we are using Windchill 9.1 M050 with Solidworks 2010 SP4.0.  Eventually we will be migrating to Windchill 10.1 and Solidworks 2013.  We also run various versions of Pro/E (Wildfire 3, 5, and Creo2).  We do run Solidworks 2011 and 2012 as well, just not with Windchill.

My issue is as follows: when renaming components within Windchill, we encountered an issue with an assembly (approximately 850 unique components) opening up missing the recently renamed components. They are listed in the tree with the old name and supressed.  To make matters worse, it's not a consistent error and the error cannot be recreated with any sort of repeatability.  After components are renamed, the assembly may or may not recognize the name change.  And even if the assembly pulls up clean, it may not the next time it is accessed or downloaded to the workspace.  We've tried removing and recreating workspaces, had other users tried to repeat the error, but it seems to be completely random when it occurs.  Has anyone experienced this?   If the error could be repeated with any consistency, I would at least be a bit relieved that we could diagnose the source, but it appears to be completely random.
