The conditions "would_be_heir_under_law" not work

[Adwa]

Hey guys, I want to rebuild primogeniture into a kind of weighted elective, like byzantium
Here is the code

elector_vote_strength = {
    days = 1
    additive_modifier = { #The heir of primogeniture
        value = 10
        FROMFROM = {
            would_be_heir_under_law = { who = FROM law = primogeniture }
        }
    }
}

elector_selection = {
    days = -5         #If below 0, ROOT is not valid to be an Elector.
    additive_modifier = { #The heir of primogeniture
        value = 1000
        FROMFROM = {
            would_be_heir_under_law = { who = FROM law = primogeniture } 
                                 #Both "who = FROM" and "who = ROOT" is same here
        }
    }
}

Please focus on "would_be_heir_under_law", in this case, I expect it will always target on the heir of primogeniture

For example, Kindom of England lead by William

When Robert is not the heir, everything alright, he is seen as the heir under primogeniture

But when Robert become the heir of elective, he immediately lose the position, he's not heir of primogeniture anymore

Does anyone know what happen or how can I fix it?

Report it as a bug, I'd say.

I'm having a very similar problem, except that only Robert has the modifier on himself, and nobody else considers it?

I solved it with the following code.

           OR = {
               FROM = { is_primary_heir = ROOT_FROMFROM }
               FROMFROM = {
                   would_be_heir_under_law = { who = ROOT_FROM law = primogeniture }
               }
           }

It is a bit of a bypass, but you retain the status when you are the first choice. However, if the primo heir isn't the first choice, the other guy who is first choice also gets the status. For me that is alright, because it gives a plus 50 in the candidate vote score with the tooltip "Is the rightful heir". In an elective succession both the picked candidate as the primo character could be seen as the rightful heir. It gives a bit more stability to the elective process as well. But I can understand is this wouldn't work for you.
