Subject: Fixed CompilePGraphsAction that gave a NullPointerException
X-Git-Tag: v1.43.0~136^2~662

Fixed CompilePGraphsAction that gave a NullPointerException

A worker thread with a null displayed tried to compile the pgraph for
ontology definition files. Ensuring that a default display is used in
such cases fixed the issues.

An error message mentioned missing dependencies if the ontology file
containers syntax errors. Thie message now mentioned problems in the
ontology file instead.
