That's what I tried, but only the last added result would work, don't know what I did wrong then if it should work.

Edit: If anyone ever finds this with the same question, then here's my current solution to multiple results with multiple handlers:

local filters = {
        [self.onCombatEventDmg] = {
            ACTION_RESULT_DAMAGE,
            ACTION_RESULT_DOT_TICK,     
            ACTION_RESULT_BLOCKED_DAMAGE,
            ACTION_RESULT_DAMAGE_SHIELDED
        },
        [self.onCombatEventDmgCrit] = {
            ACTION_RESULT_CRITICAL_DAMAGE,  
            ACTION_RESULT_DOT_TICK_CRITICAL 
        },
        [self.onCombatEventHeal] = {
            ACTION_RESULT_HOT_TICK,
            ACTION_RESULT_HEAL
        },
        [self.onCombatEventHealCrit] = {
            ACTION_RESULT_CRITICAL_HEAL,
            ACTION_RESULT_HOT_TICK_CRITICAL
        }
    }
    local nsInc = 1
    for k,v in pairs(filters) do
        for i=1, #v do
            EVENT_MANAGER:RegisterForEvent(self.name..nsInc, EVENT_COMBAT_EVENT, k)
            EVENT_MANAGER:AddFilterForEvent(self.name..nsInc, EVENT_COMBAT_EVENT, REGISTER_FILTER_COMBAT_RESULT , v[i], REGISTER_FILTER_IS_ERROR, false)
            nsInc = nsInc+1
        end 
    end

I could reduce the need for IFs in LUA to checking whether I need to create arrays or not, which should be a major improvement I guess.
