I am in the process of re-reading the excellent Core JSF book by Geary
and Horstmann. (I had initially only skimmed it having already read 3
other JSF books.) There are some interesting nuggets in there
including the following:
According to them, you can do this with <h:commandButton> and a
combination of action and actionListener.
<h:commandButton image="foo.jpg" actionListener="#{backer.listen}"
action="#{backer.act}"/>
I was suprised that you can apparently get the mouse click coordinates
from the listener ... you can then set a variable in the backer so
that your action method can use it in navigation (if that's what you
need.)
public void listen(ActionEvent e)
{
...
Map requestParams = context.getExternalContext().getRequestParameterMap();
int x = new Integer((String)requestParams.get(clientId + ".x")).intValue();
...
}
There is more great stuff like this in Core JSF so check it out!
