All,

I have the following function that I call from all of my rules. When I execute this function, I need to retract that object from working memory. The problem is that when I insert the comment line below I get a compiler error saying that I can only issue a retract on fact handles.

Here is an example of my rule plus the function:

rule "QTY Percentage tolerance - Approval"
    salience -25
    no-loop true
    when
        rtvHeader : RtvHeader( totalAmount : totalAmount, status not in ( StatusConstants.MATCHED, StatusConstants.APPROVAL) )
        repaymentCode : RepaymentCode( code == "QTY", matchApprv == "Y", tolDollar ==0, tolPercent != 0, tolPercent : tolPercent )
        qtyOutput : QTYOutput( sumRTVQty : sumRTVQty , sumCmAndRnr : sumCmAndRnr )
        eval( qtyPercentage(qtyOutput, totalAmount, tolPercent) )
    then
        System.out.println("QTY Percentage tolerance - No Approval");
        rtvHeader.setStatus(StatusConstants.APPROVAL );
        openRTVLines(drools.getWorkingMemory(), drools.getWorkingMemory().getQueryResults( "Open RTV Lines" ), StatusConstants.MATCHED_WITHIN_TOLERANCE);
end

function void openRTVLines(WorkingMemory workingMemory, QueryResults results, String status)
{
    System.out.println( "We have " + results.size() + " Open RTV Lines" );
    for ( Iterator it = results.iterator(); it.hasNext(); ) {
        QueryResult result = ( QueryResult ) it.next ();
        DetailLine line = ( DetailLine ) result.get( "line" );
        line.setStatus(status);

        // I need to add this in
        // workingMemory.retract(line);
    }
}

Thanks in advance,

Ron
