ListProperty is not iterable

[Mehmet Yilmaz Codes]

Any help appreciated:

File "kivytest.py", line 238, in on_login_success

     self.loginevent.update_test_selection("Ya!")

   File "kivytest.py", line 64, in update_test_selection

     self.dispatch('on_update_tests',value)

   File "kivy/_event.pyx", line 695, in kivy._event.EventDispatcher.dispatch (kivy/_event.c:6970)

   File "kivy/_event.pyx", line 1168, in kivy._event.EventObservers.dispatch (kivy/_event.c:12154)

   File "kivy/_event.pyx", line 1092, in kivy._event.EventObservers._dispatch (kivy/_event.c:11729)

   File "kivytest.py", line 144, in updatetests

     self.drops = ListProperty([])

   File "kivy/properties.pyx", line 397, in kivy.properties.Property.__set__ (kivy/properties.c:4680)

   File "kivy/properties.pyx", line 695, in kivy.properties.ListProperty.set (kivy/properties.c:10155)

   File "kivy/properties.pyx", line 596, in kivy.properties.ObservableList.__init__ (kivy/properties.c:7512)

 TypeError: 'kivy.properties.ListProperty' object is not iterable

I am confused, why is a listproperty not iterable?

Does this have something to do with it being initalized and "copying"?  I want to empty the property here if there is any data

Thanks,

M

Set it to [], not ListProperty([]). You're trying to instantiate a new listproperty, but actually passing this as a setter argument to the old one, which promptly fails because ListProperty is indeed not iterable.

Excellent, thanks!
