[rules-users] LHS function call

[mark.mcnally at comcast.net]

Hello,

I get the following error message when attempting to use a function call on the LHS a rule:

    "unable to resolve method using strict-mode: java.lang.Object.normalizedLoad2(...)"


My rule and function:

<code>
rule NarrowByParticipantLoad 
    dialect "mvel"
	salience -75
	when
	$nd1 : NurseDetails()	
	$nd2 : NurseDetails()	
	eval(normalizedLoad2( $nd2.hoursPerWeek, $nd2.assignmentCount ) >  
                normalizedLoad2($nd1.hoursPerWeek, $nd1.assignmentCount )) 
	then 	
		retract( $nd2 );
end

function double normalizedLoad2( int hoursPerWeek, int assignmentCnt ) {
	if (hoursPerWeek == 0) {
		return 0.0;
	}
	return  (double)assignmentCnt / (double)hoursPerWeek;				
}

</code>

I am using v 4.0.1.   It was my understanding that this should be legal.  Is it obvious what I might be ding wrong here?

Thank you, 
Mark
