I think what's needed in toscawidgets/core.py Widget is something like
the following, taken from turbogears/widgets/base.py Widget.display():
# logic for managing the params attribute
for param in self.__class__.params:
if param in params:
param_value = params[param]
if callable(param_value):
param_value = param_value()
else:
# if the param hasn't been overridden (passed as a keyword
# argument inside **params) put the corresponding instance
# value inside params.
param_value = getattr(self, param, None)
# make sure we don't pass a reference to mutables
params[param] = copy_if_mutable(param_value)
But I can't figure out where to put that sort of logic in core.py.
Maybe in Widget.update_params(), which almost seems to be handling the case.
