Hi Chris, thanks for the link.
At first, It seemed like the code in turbogears.controllers.py just
iterates through those widgets and extracts all the relevant
javascript and CSS files and strings, but it didn't add the widget
itself to the template.
Then I saw how it does add the widget, but it changes the name in this
block:
for i in include_widgets_lst:
widget = tg_util.load_class(i)
if isclass(widget):
widget = widget()
include_widgets["tg_%s" % i.split(".")[-1]] = widget
So, my original widget was called hw, but in my template, I needed to
refer to it as tg_hw.
I'm posting this here for future reference.
Matt
