Hmm... I tried a widget very similar to the one you're trying and I
couldn't reproduce the problem. Additionally, these templates should
not be autoreloaded. In the code above, it sets cls.template to the
Template class itself.
This is what happens in kidsupport:
def transform(self, info, template):
if isinstance(template, type):
tclass = template
else:
tclass = self.load_template(template)
Unless that if statement is wrong (and I didn't think it was), if it's
passed a template class directly it will just use that, otherwise it
will run load_template (which is also responsible for the refreshing).
So, kidsupport shouldn't be doing any reloading of the template
already.
