[rules-users] "or" operator with only one condition??

Hi Guys, Although doesn't make sense, is there any problem if I write the next rules? XML: <rule name="OR with one condition"> <lhs> <or> <column object-type="RAFact"> <literal evaluator="==" field-name="type" value="groupId" /> <literal evaluator="==" field-name="value" value="6" /> </column> </or> </lhs> <rhs> System.out.println("Something..."); </rhs> </rule> DRL: rule "OR with one condition" when or RAFact( type == "groupId" , value == 6 ) then System.out.println("Something..."); end In my tests, it seems the XML version is accepted (and correct) because the parser ignores the 'or'! Thanks in advance, Bruno Duarte
