[jboss-jira] [JBoss JIRA] Closed: (JBRULES-1030) NPE Building Rule with inexistent field

[Edson Tirelli (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBRULES-1030?page=all ]

Edson Tirelli closed JBRULES-1030.
----------------------------------

    Resolution: Done

Fixed and added unit test. For now we are raising a generic RuntimeDroolsException with a specific message stating the field that was not found for the given class. Example:

Caused by: org.drools.RuntimeDroolsException: Field/method 'xyz' not found for class 'org.drools.util.asm.TestBean'

In the future, if needed we can replace that for a specifc exception class.

Thanks for reporting.

> Create a rule that references a field that does not exist. The code at line 105 of package org.drools.base.ClassFieldExtractorFactory is not checking for nulls.
> The problem is that there is no error message and no way to know what the problem is except using the trial and error method.
