Hrmpf. It's a bit misleading then that it reads in the source
"""
@only_if_initialized
def retrieve_javascript(self):
#XXX: Should be deprecatred and use only retrieve_resources
from toscawidgets.resources import JSMixin
return filter(lambda r: isinstance(r, JSMixin), self._resources)
"""
without any comment on the retrieve_resources method that it's currently
not in use.
Regarding the post-initilization-JS: For my usecase at hand, I don't
think I need that.
