Hi Samuel,
your rules seem to use the magic property tops:definesStatements, which
only works when you have a file open in TBC, because it needs to access
the currently active query graph. Try to avoid using this magic property.

Does anyone have an idea what may cause this error? I get exactly the
same error also from the plugin "org.topbraidcomposer.spin".
Thanks in advance.
