@PropertyRactive not working with too many attributes

[MrDrool]

Hello,

I have a strange problem with @PropertyReactive.

In reality my Class has 57 attributes(Strings, Booleans, Calendars, Subclasses etc), but for example:

@PropertyReactive
ClassA{
String a;
String b;
}


rule "rule1"
when
classA: ClassA(a == "a")
then
modify(classA){ setB("b")};
end

rule "rule2"
when
classA: ClassA(b == "b")
then
System.out.println("check");
end

My problem is that rule 2 worked as expected as long as I did not change ClassA.
But after I added a new attribute to ClassA Rule 2 stopped firing:

@PropertyReactive
ClassA{
String a;
String b;
ClassB c;
}

I have played around a bit and noticed the following:
- Removing ClassB from ClassA -> rule2 is working again
- Using @ClassReactive instead of @PropertyReactive -> rule2 is working
- Removing another attribute from ClassA and adding ClassB ->rule2 is working
- using retract() and inseart() -> rule2 is working

- Adding another simple attribute like String -> rule2 is not working
- using update() instead of modify -> rule2 is not working


=> with 58 attributes in my class rule2 will stop working with @PropertyReactive. Is this too much? Is the class too complex? Is this a known limitation?

I can't use @ClassReactive because I have a few hundreds rules and I get problems in other rules with endless loops, so I guess I have to stay with retract() and insert()?

I'm still on Drools 7.74.1

Best regards
