[rules-users] rule error

[Fnu Mahalakshmi]

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
m
