I wanted to add the "fmc" profile to my root container, so I clicked on it in the properties view to add it. However I didn't also press shift, which apparently is required to set multiple profiles on a container. So the current "fabric", "jboss-fuse-full" and hidden ensemble profiles were apparently removed from the container. This means the zookeeper server was immediately shut down, making my fabric unavailable. Think the only recovery is to run fabric:create again. Couple suggestions:

1) Do a confirmation dialog that states what existing profiles are on the container and what they'll be changed to.
2) Have the profile property page multi-select by default (think this would be better) so that a user would have to explicitly un-highlight a profile to remove it from a container.

Option 2 is probably better really..
