we also need plone.api here. in plone 5, this is even a core dependency, although it isn't used in the core

[petschki]

I'll remove plone.api so it can be better forwarded to Plone 5.0

@petschki @thet plone.api is not allowed to use in core. We ship with it but we can't use it. Please amend the code to use the plone.app.registry lookups.

@jaroel we need to set up a jenkins check to make sure plone.api is not used in the core. Otherwise we will not be able to control this. This use case is more complex than grok since we ship with plone.api but we can't use it.

@tisto regarding plone.api: that change aims only for the 1.x branch, which will never be part of the core. However, I'd also prefer the plone.app.registry lookup, since this package is quite close to the core.

@thet right. plone.app.widgets has been merged by @vangheem into other plone packages...ok, then I don't care. ;)

@petschki - the travis build errors can be fixed with that commit: 87e924c

@thet cool ... tests are passing now. note: I've changed the default time interval back to 5 minutes
