p:password doesn't redisplay prefilled model value

问题

i have my managed bean like this :

@ManagedBean 
@SessionScoped
public class utilisateur implements Serializable {

    private String login ="yous" ;
    private String password ="yous";
    ...
    ...

}

and my login.xhtml

<h:outputText value="login: " />  
<p:inputText value="#{utilisateur.login}"  />  

<h:outputText value="password: " />  
<p:password  value="#{utilisateur.password}"  />  

so with this configuration the password must be shown by default like **** (yous) in p:password but it shows empty.

回答1:

This is the default behaviour for security reasons. You need to explicitly set the redisplay attribute to true if you need to display the password from the model whenever it's been submitted or preset.

<p:password value="#{utilisateur.password}" redisplay="true" />  

See also the <p:password> VDL documentation, it's the one before last attribute.

redisplay Boolean flag indicating whether or not a previously entered password should be rendered in form. Default is false.
