Hi, I've been learned Nevow mainly by instinct, so this may be documented somewhere and I can't find it. If I wanted to produce XML that looks something like: <tag1> <tag2/> <tag3/> <tag4/> <tag4/> ... <tag4/> </tag1> how would I do it? I am using render = directive("sequence") for tag1, and pattern = "item" for tag4. This works fine for: <tag1> <tag4/> <tag4/> ... <tag4/> </tag1> but I want to include those extra tags. I thought setting render = directive("heading") on tag2 and tag3 might work, but it gives the following error: File "/home/mary/src/Nevow/nevow/accessors.py", line 53, in child return self.original[int(name)] exceptions.ValueError: invalid literal for int(): header after a long traceback. The two attached files should demonstrate the problem: noheader.py works, header.py gives the error mentioned. Is this a bug or am I simply going about this the wrong way? -Mary
