[Grok-dev] ListSequenceWidget - How to change the sequence

[Sascha Boch]

That looks promising. However (again...), I run into the next issue. It 
seems there is a problem with hurry.resource:

ComponentLookupError: (<InterfaceClass 
hurry.resource.interfaces.ICurrentNeededInclusions>, '')

Is it related to my installation? I had to install z3c.listjs with 
easy_install. Buildout would not do it if I included it in the requirements 
section of setup.py. Therefore, I have some eggs in /usr/local/lib/... vs. 
the .buildout directory.
