Yes, I'm suffering with a similar problem running RAD 7.5 with WAS 7.0. I get "Workspace configuration consistency check is disabled." which is probably just as bad.
I can only assume that if the consistency check was enabled it would return false in the same manner as yours. I've looked all day for some information about how to enable this within websphere, then i might actually get something in the log files to figure out what's going on...
Anyone heard of this before? What's a workspace anyway?
I'm not sure if I approve of this interruption. But this tiny ad checks out:
