[rules-users] Call class method from LHS of a rule

[orchid]

Hi All,

I'm trying to call a class method from the LHS of a rule in the following
way:

public class Cheese{
  private string type;
  //setters and getters
  public boolean existsInShop(String shop){
    ...
    return true;
  }
}

I would like to call the method "existsInShop" from a rule:

Rule "Rule1"
  when
    $c:Cheese(type == "chedar", existsInShop "shopName")
  then
    System.out.println("Rule1 is fired");
end

I get the compilation error: "no viable alternative at input "shopName" in
rule "Rule1" in pattern document". How can I call the method from the rule?

Thanks in advance.
