Hi, try:
yourListView.setReuseItems(true);
>From the JavaDoc:
*WARNING:* though you can nest ListViews within Forms, you HAVE to set the
setReuseItems property to true in order to have validation work properly. By
default, setReuseItems is false, which has the effect that ListView replaces
all child components by new instances. The idea behind this is that you
always render the fresh data, and as people usually use ListViews for
displaying read-only lists (at least, that's what we think), this is good
default behavior.
However, as the components are replaced before the rendering starts, the
search for specific messages for these components fails as they are replaced
with other instances. Another problem is that 'wrong' user input is kept as
(temporary) instance data of the components. As these components are
replaced by new ones, your user will never see the wrong data when
setReuseItems is false.
