Hi,

 

I want to just depict ‘&&’ and ‘or’ in my rules and did as follows:

 

rule "Update value”

no-loop true

      when

            $y :Y(name != "")

            $x: X(status != "")

            $z : Z( y == $y, x == $X,(status == “yes" or status == "no"))

      then

            modify($z){};

 

end

 

The above does not work. Is it not valid to write as above??

How else can I depict “or” ? relation?

rule "Update value"

no-loop true

      when

            $y :Y(name != "")

            $x: X(status != "")

            $z : Z( y == $y, x == $X,(status == “yes" , status == "no"))

      then

            modify($z){

setOutput($z)};

 

end

 

 

even this does not work.

 

I also want to add all the values specific to this condition and just print them out in my output file.

So I tried adding it to a list (which is done by setOutput().

But here I keep getting multiple entries for the same value.

For eg. {a,b,c } //are instances of type z

They keep getting added again and again. Should it not process input only once????

 

 

Please help.

 

Thank you
