Rebel dispenser_touch_trigger help!

So, I'm making this traditional payload cart.
Follow the instructions on valve's wiki. Everything works well.
I create a dispenser_touch_trigger as big as the cap_area, give it a trigger texture.
Parent it to my bomb_train.
Build and play the map...

It won't heal me. No matter what size, texture, parent, name or blessing I give it, it simply won't heal me. I also tried with both teams, no go.

Is there some untold manipulation that needs to be done for it to work? :O

 

Do you also have a mapobj_cart_dispenser?

 

Actually I don't.
I thought that was used only to show a nice beam between the dispense touch trigger and the player!
But I see you have to give it a team value, so it must be what's missing.
AAAHHH! Noobish mistake.
