MultiLine container element binding problem

[Mike Pokraka]

Hi Nigel,
The version question was very relevant, prior to NW04 there is no indexed
access to multiline containers. On 630 or lower I am not completely sure
it this was even supposed to work, my guess was that this sort of binding
should not be possible.
I've not tried it, so I might be wrong. The usual way I handle it is to
use an 'Append to table' type binding into a new multiline element. This
also helps debugging as you can see the before and after.
Cheers,
Mike
