[rules-users] General rules in spreadsheet.

Hello, I want to use StatelessSession with spreadsheet. I wrote few rules in DRL, but I cant do it in spreadsheet. First I want to present rules and class that is used by rules: public class CProduct { private String name; private int value; public CProduct () { name = "empty"; value = 0; } public CProduct (String name, int value) { this.name = name; this.value = value; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getValue() { return value; } public void setValue(int value) { this.value = value; } } Rules: rule "Case A" salience 1 activation-group "g1" when p : CProduct( name == "A" ) then System.out.println("Special product: " + p.getName()); end rule "Case B" salience 1 activation-group "g1" when p : CProduct( name == "B" ) then System.out.println("Special product: " + p.getName()); end rule "Case general" salience 0 activation-group "g1" when p : CProduct( ) then System.out.println("Normal product: " + p.getName()); end Using stateLessSession, salience, and activation-group I can determine, that only one rule is going to be fired for each CProduct. And with salience param, I can determine priority (it is important to get special products first). Now I am going to write those rules in spreadsheet. But I can't define rule "Case general". CONDITION ACTION ACTIVATION-GROUP PRIORITY p:CProduct name System.out.println("$param"); Rules names Product name what to print Case A A Special A G1 1 Case B B Special B G1 1 General case normal G1 0 But when I am going to use the spreadsheet, I get this error: "p cannot be resolved" Problem disappears, when I fill "Product name" in "General case". But I want it to be empty, because I want to fire rule "General case" when rules "Case A" & "Case B" won't fire for any object's name. Thanks, Tom.
