[rules-users] DSL Build Problem

[Wolfgang Laun]

The error is raised during DRL compilation - so it is not a DSL build problem.

If you use the resulting DRL line instead of the DRL phrase "Write
qualifyingPoints..."
by prefixing it with '>' you should see the same error.

Do you have the same Drools runtime in the classpath for RSA and Eclipse,
especially the MVEL jar?

Not causing your problem, but it would be healthier to call the setter:
modify (Result){ setQualifyingPoints($var01 * $var02) };
