在jsf中单击第一个按钮后，在第二个，第三个h：commandbutton上未调用操作方法

Question

I have a JSF page that I intend on using to edit a user's information. All of the components needed for editing the user are included in the same pag an dI'm using the render attribute to determine which components should be rendered. The first panel group is rendered and when you enter the users login name and click the button everything works just fine and the second panel group is displayed and you can change the users information in the text fields. The problem comes in with the clicking the button in the first tab of the accordian panel, it doesn't work. I've tried request scope and view scope and have the same problem when using either one.

    <f:view contentType="text/html">

                                                <h:commandButton value="Cancel Changes"></h:commandButton>    
                                            </h:panelGrid>
                                    </p:tab>

The command button with the value "Save Changes" is the button in question since the bean method is never called.

@ManagedBean
@ViewScoped
public class AdminManagedBean implements Serializable {
public String saveNameChange(){
    log.info("save Name called");
    this.editUser = ssb.updateUser(editUser);
    return "edituser";
}

The method "saveNameChange" is not being called when the button is clicked. Any help wouldbe greatly appreciated.

Answer 1

In the process of editing the page and bean for posting on SO the problem was discovered and it had nothing to do with the JSF components. The problem was two fold,

1) A developer had changed the size of a field in a table in the db but not in the entity class associated with that table which was causing validation to throw an error message. 2) The styling being used was preventing the error message from the validation from being displayed.

Solution: I updated the entity class, corrected the styling and the buttons are now working properly.
