No, it's definitely the whitespace. If I remove the
whitespace, it
works quite happily. As it is, I've instructed
AddParsedSubObject to
ignore everything that isn't a TableCell (or descendent)
and it's
working, but I'd rather write something that's less of a
hack.
Sorry, I prolly wasn't very clear. HeaderTemplate and
ItemTemplate both
render into TableRow controls, the RepeatingInputRow control
creating a
Table. The table construction isn't the issue, it's
definitely the
whitespace LiteralControl instances in the code-forward.
Most odd.
Thanks for your suggestion, though.
