Hi
Gregg,
I'm using the release version 1.0.2 in which the leadingDescShown and
trailingDescShown attributes of selectOrderShuttle don't seem to be
working - the description boxes remain empty. Was this bug responsible
for this too?
Thanks,
Steve

Apparently two more private generated

TrShuttleProxy._orderList and TrShuttleProxy._orderTopBottomList are
also affected by this bug in the selectOrderShuttle component. I have
also patched and successfully overridden these functions as follows
