[rules-users] Error using multiple evals

[Wolfgang Laun]

Usually the result of an accumulate is tested right there in the
pattern matching that object:
...
            Number($i1 : doubleValue > (getNodeCount()*0.35) )
            from accumulate(...

Hopefully, getNodeCount() is a DRL function or an imported static method.
