simple constraint. The problem only happens with constraints that use semantic code.<br> I tracked down the problem and it is in the LogicTransformer that is used when an "or" CE is present.

One question do you get different reslts if you do the folowing for the first rule:<br><br>Message( message == "somethingDifferent" ) # this should never match<br><br>All I did was eliminate the eval and the explicit call to equals
