[rules-users] 5.2.0.M2 issue using import functions

[Wolfgang Laun]

This was a regression due to substantial changes of the DRL compiler. MVEL
strict mode has nothing to do with this.

I'm not sure when the fix was deployed, but you should have this MVEL2 jar
in your classpath - check the size. And you may need a Drools built from the
latest of the 5.2.0.M2 branch.

... 711693 2011-05-02 14:12
./org/mvel/mvel2/2.1-SNAPSHOT/mvel2-2.1-20110501.033205-24.jar
... 711693 2011-05-02 14:12
./org/mvel/mvel2/2.1-SNAPSHOT/mvel2-2.1-SNAPSHOT.jar

Tested successfully with
   import function java.lang.Math.*;
   rule x
   when
       $i: Imaginary( eval(atan2(im,re) > PI/4.0) )
   then end
