Comment:
I don't think this is a bug, but a misunderstanding of how Python `*args`
work. If you define your method with
{{{
def create(self, tg_error=None, *args, **kw)
}}}
and then call `/create/45`, this is translated to `create(45)` and this
will result in `tg_error=45` and `args=[]`. You probably thought that args
should be `[45]` but this is not the way how it works. To solve this,
define your method like this:
{{{
def create(self, id=None, tg_error=None)
}}}
And then instead of checking for `len(args)==1` and using `args[0]`, check
for `id is not None` and then use `id`.
