Execution of rule is failing when modify an object - jboss

Question

In the below rules I expect Rule2 is fire because I am modifying customer name to mahesh. But when I execute Rule2 is not firing but Rule3 is firing. Am I missing anything here
rule "Rule1"
lock-on-active true
salience 95
when
$c:Customer($customerName:customerName)
then
System.out.println($customerName+" =======2========");
modify($c){
setCustomerName("mahesh");
}
System.out.println($customerName);
end
rule "Rule2"
lock-on-active true
salience 85
when
$c1:Customer($customerName:customerName=="mahesh");
then
System.out.println($customerName+" Rules Name is 1 - " + drools.getRule().getName());
$c1.setCustomerName("mahesh456");
update($c1);
end
rule "Rule3"
lock-on-active true
when
$c:Customer($customerName:customerName)
then
System.out.println($customerName+ "***** ");
end

Answer 1

What lock-on-active does is to prevent a rule to be activated if the agenda group where the rule is defined is already active.
In your case, because you was already executing the rules (fireAllRules) the MAIN agenda group (which is the group that both of your rules belong to) was already active. This mean that the second rule activation is going to be cancelled by Drools.
You can find here a more in depth explanation.
Hope it helps,
