Does import but works with no effect; Bundle does not compile in plone 5

Hi!
Cloned via git, bootstrapped, included in buildout as dev package, imported into plone.
@@minimalpatterndemo is accessible but does not work - only 3 times "uh-what".
Resource registry shows the resources and the bundle correctly.
Trying to compile the bundle results in "NetworkError: 404 Not Found - http://localhost:8080/Plone/pat-base.js"

I noticed that in Mockup the name for the base component is "mockup-pattern-base" and not "pat-base" as in the config.js of mockup-minimalpattern. May that be the cause?

Best regards
Volker

Start with config.js and the registered resources and bundle for @@minimalpatterndemo. Compare the configured base component name with Mockup's mockup-pattern-base and reproduce the bundle compilation request for pat-base.js. Done means the bundle compiles without the 404 and the pattern no longer produces repeated "uh-what" output.
