If I cannot use the @ManagedProperty annotation with @Named, because @ManagedProperty doesn't work in CDI(?), then how do you pass params in the URL to the facelets client? In my code, I want to pass javax.mail.getMessageNumber() to details.xhtml through the "back" and "forward" buttons.
I understand that @Inject should be used, but what is being injected and how, please?
From the glassfish logs, id is always 0, which is quite odd. Even when "forward" is clicked, id never gets above 1 no matter how many times the button is clicked. Of course, that's merely a symptom of the problem. The desired output, of course, is to advance to the next Message.
Perhaps put the Message, or at least the int, into the session?
The client as so:
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

and the bean as so:
package net.bounceme.dur.nntp;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.enterprise.context.RequestScoped;
import javax.faces.bean.ManagedProperty;
import javax.inject.Named;
import javax.mail.Message;
@Named
@RequestScoped
public class Detail {
private static final Logger logger = Logger.getLogger(Detail.class.getName());
private static final Level level = Level.INFO;
@ManagedProperty(value = "#{param.id}")
private Integer id = 0;
private Message message = null;
private SingletonNNTP nntp = SingletonNNTP.INSTANCE;
public Detail() {
message = nntp.getMessage(id);
}
public int forward() {
logger.log(level, "Detail.forward.." + id);
id = id + 1;
logger.log(level, "..Detail.forward " + id);
return id;
}
public int back() {
logger.log(level, "Detail.back.." + id);
id = id - 1;
logger.log(level, "..Detail.back " + id);
return id;
}
public Message getMessage() {
return message;
}
public String getContent() throws Exception {
return message.getContent().toString();
}
}
