misleading error on UI

Description of problem:
I was trying to add a new container from webUI. So I created a local docker compute-resource. Test-connection was successful. I added a docker repo with busybox image.

But when I tried a to create a new container, I got following message:

"False You need a Docker compute resource in order to create containers. Please add a new one and try again. "

This is misleading error.
