Re: Java for generating suggestion-list

[David Legg <da...@searchevent.co.uk>]

In searching for information on how to use Java generated data as a 
*suggestion* list in a CFORM multivaluefield I came across the 3 month 
old email thread below.

I am interested in using this... did it get resolved?

Regards,
David Legg
