Mob killed and attack events are swapped in MCreator 1.7.8

Mob killed and attack events are swapped!(This bug wasn't fixed in 1.7.8) See this in your custom code!

This code of attack event:

    public boolean attackEntityAsMob(Entity entityIn)
    {
        if (super.attackEntityAsMob(entityIn))
        {
            if (entityIn instanceof EntityLivingBase)
            {
            }

            return true;
        }
        else
        {
            return false;
        }
    }

For example mob can poisons entity(in easy Difficulty mob can not poisons entity) :

    public boolean attackEntityAsMob(Entity entityIn)
    {
        if (super.attackEntityAsMob(entityIn))
        {
            if (entityIn instanceof EntityLivingBase)
            {
                int i = 0;

                if (this.world.getDifficulty() == EnumDifficulty.NORMAL)
                {
                    i = 7;
                }
                else if (this.world.getDifficulty() == EnumDifficulty.HARD)
                {
                    i = 15;
                }

                if (i > 0)
                {
                    ((EntityLivingBase)entityIn).addPotionEffect(new PotionEffect(MobEffects.POISON, i * 20, 0));

            }

            return true;
        }
        else
        {
            return false;
        }
    }
