[Pathfinder] Mount and Grapple

[Rootle]

Hey,
this is my first post, so be nice ;)

I'm having a summoner and am using my Eidolon as a Mount. Now I'm planning to get it the Grab Evolution to grapple foes. So here are my Questions:
1) Do I get unmounted when my mount starts a grapple?
1.1) Can I do a Ride check (DC?) to avoid being unmounted?
2) Can I do an normal Attack in the consecutive Round as I am not a part of the grapple?

One: I would say you wouldn't but it really depends on how it is grappling or what it is grappling with. If it was doing it with something smaller I would say no, but anything the same size I would likely require you to make a ride check to avoid being dismounted(which answers question 1.1, yes you can)

Two: I would say yes, though you will still have a chance of hitting your eidolon.

Anyway, this is probably stuff you would want to go over with your dungeon master and figure out what they have to say.
