Thanks, Tony, for pointing me at the range[] operator. Could you elaborate a bit on how you use it. So far I've gotten by using the <$list> widget, but your approach might be more efficient than mine.
Here's what I'm doing when looping through JSON data <$set name="actions" filter="[all[current]indexes[Actions]sort[]]" > <!--- indexes[] doesn't necessarily provide the correct sorting order --> <$set name="actionCount" filter="[<actions>split[ ]count[]]" > <!-- needed later for determining rowspan value --> <!-- start loop through actions; fetch array indexes --> <$list variable="currentAction" filter=<<actions>> > ... </$list> </$set> </$set> Speaking of tables, is there anything to be aware of, as to how TW injects HTML tags? I can't seem to get <tr> and </tr> right in my dynamically created nested table. I have delegated some code to conditionally executed macros, and Chrome seems go get confused, when a </tr> is used at a position it doesn't like. Thanks again Werner Am Donnerstag, 27.
