[protege-owl] SWRL Racer problem

Hi Martin and everyone,
In a previous post I reported a bug with Racer, SWRLtab and computing inferred
types. Inferring over the ontology is fine using 'compute inferred types' until
I initiate the SWRLtab. Then I get error messages like:
DIG Reasoner Error: Undefined individual name|query:comumnNames|in ABox |
when computing inferred types through Racer.
I was wondering if you had heard any feedback from this bug report? It has
become a major problem as I can't continue with my research until I can resolve
why this is occurring. I though it might have been an anomalous glitch in 414
but I have just tested it with the latest version (430) and the same thing keeps
occurring. I have used 3 different machines, I have downloaded RacerPro and Jess
again and did a clean install for both but still the errors happen.
I can send a screenshot showing the problem. One such incident happened after
opeing a new project and creating 2 classes (no restrictions, instances, etc),
setting up the SWRLtab and activating it. At this stage computing inferred types
works fine, however, anything after this ends in the error message (the screen
shot shows a simple rule is written but not yet sent to the Jess engine). I
tried it using the 'collabborativePizza' ontology supplied with version 430,
after deleting the classes that made it inconsistent I set up the swrlTab and
imported the SWRL ontologies...the error occurred as soon as I tried to compute
I have an old version on one of the machines (399) and the errors do not occur??
Any suggestions or answers would be extremely appreciated!
