Replying to [comment:1 kmtracey]:
> I've not encountered any problem following the current docs, omitting
parentheses. Therefore I believe the doc as it currently is is correct:
parentheses are not required. What in the source gave you the impression
that they are?
Sorry then. Their must be something screwy in my configuration because
after adding the parentheses the template system stopped crashing for us.
I got the idea after looking at template/_init_.py in the Library.tag
function which starts like this:
{{{
def tag(self, name=None, compile_function=None):
if name == None and compile_function == None:
# @register.tag()
return self.tag_function
elif name != None and compile_function == None:
if(callable(name)):
# @register.tag
return self.tag_function(name)
}}}
I read the if and it gave me the idea to add the parens which got my
system working. Now reading further I see in the elif clause if "name" is
callable it should just work without the parens. I'll be more careful
before opening an issue in the future. Also if I can track down exactly
what's causing the weird behavior on my system I'll post it here as a
cautionary tail for others who might run into the same problem.
Thanks,
Jim
