[rules-users] General rules in spreadsheet.

[tom ska]

Hello,
well, You are right, but what if I want to use object's method in ACTION
section like this:




CONDITION ACTION ACTIVATION-GROUP PRIORITY    p:CProduct          name
System.out.println(p.getName()
+ " " + "$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
In this case, I want for each CProduct fire it's method in ACTION column
(like in rule "Case general" for DRL.
Thanks :)

>> Hello,
>> I want to use StatelessSession with spreadsheet. I wrote few rules in DRL,

>>
>> 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.
