I am trying to force a JSF page to refresh all of its components so

trying to come from another page using a JSF hyperlink to reach the

cleared of all previous values. Any help would be appreciated.
Thanks

Create a "creator bean" that clear itsself when you are done submitting

public class AccountBean {
private Account account;

public AccountBean() {
account = new Account();
}
//setters and getters

public void submit() {
//persist to DB
account = new Account();
}
}
But how is that going to force the page to create a new view with no
values?

It reflects the backend bean. So there will be no values after you
submit....
Take a look at the submit method I sent.

A little more detail and explanation would be helpful. Thanks.


public class AccountBean {
private Account account;

public AccountBean() {
account = new Account();
}
//setters and getters

public void submit() {
//persist to DB
account = new Account(); //create a new account after
submit
}
}

Well, taking a look at this bean notice the account = new Account()
line in the submit method. That means that after an account is created
via the submit method the bean will hold a blank new account which will
hold no information whatsoever. When you visit the page all the
information will be blank. Another strategy is to remove that
line...


public class AccountBean {
private Account account;

public AccountBean() {
account = new Account();
}
//setters and getters

public void submit() {
//persist to DB
//account = new Account(); //this line is removed
}
}

and just make sure that the AccountBean is of request scope and you
will get the same functionality.
