GMapPointWidget based on PointWidget and BaseGMapWidget don't work

I followed the example showed on http://django-floppyforms.readthedocs.org/en/latest/geodjango.html#google-maps to create a PointWidget but the widget doesn't show up. However, when I use BaseOsmWidget instead, the widget appears on my form. Does anyone with the same issue?

PS.: I ran "manage.py test floppyforms" and "manage.py collectstatic" and everything is fine.

Start with the GeoDjango Google Maps example linked in the issue and reproduce the failure using GMapPointWidget with BaseGMapWidget. Compare that result with BaseOsmWidget, then run the mentioned floppyforms tests and collectstatic command. Done means the Google Maps point widget appears correctly on the form without breaking the existing checks.
