OK, I tried that and got a name error on REQUEST, so I did this instead:

print context.index_html(context, context.REQUEST)

But that gave me an error like:

Error Type: TypeError
Error Value: no arguments expected

So I tried not supplying any arguments... context.index_html(), and got the
'excessive recursion error'.

Any clues?

Thanks
