[rules-users] Exception: Conversion to long not supported for type: class org.drools.examples.BilboAndTheDwarfs$DwarfShadowProxy

[Edson Tirelli]

     Oliver,

     In you Bilbo pattern you wrote:

pos > $Ori,

     "pos" is an int attribute, while "$Ori" is bound to a Dwarf object.
     It is not possible to convert one type into the other to make the
comparison.
