Actually I would like to strongly discourage nesting WidgetsList in
this way, we end up with some problems related to naming those widgets
and their declarative_counter also I would like to suggest you a far
easier solution that actually works:
from turbogears import widgets
def common_widget():
return widgets.TextField()
class FooBar(widgets.WidgetsList):
bar = widgets.TextField()
common = common_widget()
foo = widgets.TextField()
key = common_widget()
mouse = common_widget()
for widget in FooBar():
print widget.name
output:
bar
common
foo
key
mouse
Rule of thumb of the day: never nest WidgetsList instances.
This avoids you any sort of problem.
