I've been working on an interface. The views I was getting for classes and
instances were 'wrong' (links weren't showing up as links, properties
weren't being shown, etc.), but they were showing up. I made a change to
the models I am importing, and now neither classes nor instances are
rendered (either in TBC or in the browser) and I am getting errors such as
the one attached (others are timeouts but I suspect the same problems).I am
also getting 'failure to import' warnings for some models which I am not
sure are related: http://www.linkedmodel.org/1.1/owl/schema/core,
http://spinrdf.org/spin.ui, http://uispin.org/swon, and
http://evn.topbraidlive.org/ui.
Does any of this ring a bell with anyone?
Jack
