Create a property on your class holding the ListView to store the
selected list item, and then do something like:
setCurrentRuleChain( item.getModelObject() );
where your "System.out" line is. The ListItem#getModelObject() holds a
reference to the individual model object that it is rendering.
Then, you can do somewhere else in your code:
// if not null, then we have a selection
if ( myPanel.getCurrentRuleChange() != null )
{
// do something
}
There are a few different ways to accomplish it, but hopefully this
gives you an idea.
