html:select : update bean field only if values are selected

[Ionel Gardais <io...@geomath.fr>]

Hi,

I have two select lists that I use a swaping selections (transfert one 
item from a list to another and remove it from the first)

the problem is that Struts doesn't update a bean field when a list is 
not empty but when there are selected values inside.

how to tell Struts that I need an "on-presence" update and not an 
"on-selection" as by now ?

thanks,
ionel
