This rule:

rule "Not"

when

not(

          RuleTime()

          Patient()

          )

then

      System.out.println("not");

end

produces the following errors when compiled:

[ERR 102] Line 43:5 mismatched input 'Patient' expecting ')' in rule "Not"

[ERR 102] Line 44:5 mismatched input ')' expecting 'then' in rule "Not"

But if I change it to use explicit ANDs instead of implicit ANDs it compiles and runs.

rule "NotBlock"

when

not(

          RuleTime()

and

          Patient()

          )

then

      System.out.println("notBlock");

end

Is it invalid syntax to use implicit ANDs in a not block? If so, why?

Thank You,
