ListIndex

[Jonathan Impett]

Hello,
        There's obviously something I've misconceived in my use of ListIndex. 
scheduler is a list, happily created elsewhere. At line ***, it tells me
the object does not conform to the `ListIndex' protocol. If I use Index
instead of ListIndex, it begins OK, but of course doesn't know how to
AddAfter...

        id <ListIndex> schedIndex;
        so = [schedObject create: [self getZone]];
        [so setAction:a b1:v1 b2:v2 chan:v3 time:then];
        ***schedIndex = [scheduler begin: [self getZone]];
        while (((event = [schedIndex next]) != nil) && ([event
getTime]<=then))
                        [schedIndex addAfter: so];
        [schedIndex drop];

        Any ideas?
        thanks,
        Jonathan
