    org.drools.RuntimeDroolsException: Error creating shadow fac

    Vineet Sahni Newbie

      First of all I would like to convey my thanks to Jeff who helped me resolve previous drool-custom class issue.

      Now, while redeploying and rerunning application the a drool run time shadow object creation exception is thrown as shown below.

      This does not happen if the server is restared.

      I would prefer not to do this because it would restrict our ability to deploy rules at run time. I am also listing the ErrorLIst class below.

      Thanks for your help.
