I have this widget. It does not seem to work because of the 'self.method'
member variable. I get the stacktrace below
{{{
class ReserveWorkflow(Form):
member_widgets = ['method']
params = []
template="beaker.server.templates.reserve_workflow"
def __init__(self,*args,**kw):
super(ReserveWorkflow,self).__init__(*args, **kw)
self.method = SingleSelectField(name='method', label='Method',
options=[(-1,'None')] + [(elem,elem) for elem in
model.Distro.all_methods()])
}}}

if widget.is_named:
AttributeError: 'Element' object has no attribute 'is_named'
}}}
Now if I change it to 'self.method_' (notice the trailing underscore) and
obviously change the corersponding entry in member_widgets and in the
template, then it works fine.
Not sure what the problem is. Maybe something to do with the
iter_member_widgets generator object ??
