Perhaps try and ordering constraint, I may have also fixed something
in this area for 1.1.6 so an upgrade might also help

I'm trying to setup a colocation rule so that a couple of master-slave
resources cant be master unless another resource is running on the same
node, and am getting the exact opposite of what I want. The master-slave
resources are getting promoted to master on the node which this other
resource isnt running on.
In the below example, 'stateful1:Master' and 'stateful2:Master' should
be on the same node 'dummy' is on. It works just fine if I change the
colocation around so that 'dummy' depends on the stateful resources
being master, but I dont want that. I want dummy to be able to run no
matter what, but the stateful resources not be able to become master
without dummy.

Tried that too (just not the configuration at the time I sent the email), no
effect.
Upgraded to 1.1.6 and put in an ordering constraint, still no joy.
