jsf-2

问题 I am using JSF 2.0 and Primefaces 3.2. I have a main form with a datatable and a button on each row that brings up a dialog with another data table. The dialog has its own form. When the datatable row is selected in the dialog, i process the selection and then refresh the datatable in the main form. After the refresh all my filters on the main datatable are lost. Is there a way to remember the filter values? My JSF page <h:panelGroup id="mainTable"> <h:form id="mainForm" prependId="false"> <p

问题 Background: I have a ViewScoped bean with a field named someId I have a page, somePage.xhtml with an inputText and a commandLink The value of the inputText has a corresponding field in the bean named searchValue When I click the link a method in the bean redirects to another page called searchResult.xhtml that use the same bean as somePage (although not a requirement) Before rendering searchResult the bean needs to execute a search in the database, based on the value of the inputText and the

问题 I created a simple JSF login page, and I'm trying to integrate it with spring security.

问题 I have a form with a lot of inputText, what I want is to highlight those who are not being filled with correct data. I tried to use 'component.valid' but it always return that the field is invalid (i.e. fields are always red). this is the code : <h:inputText value="#{creerPersonne1.nom}" id="nom" style="#{not nom.valid ? 'border-color:red;' : 'border-color:black;'}"> <f:validateRegex pattern="^[a-zA-Z]+$"></f:validateRegex> </h:inputText> this is the result : note that the field is also

问题 I'm currently learning about JSF 2.0 and im so glad for the existence of this conversation scope feature, which is very helpful in opening a new tab or a new window on the same page and having separate resources, not overriding one another. But im curious on how to implement this in a good way, about when to start the conversation and when to close it. In my case, i have each CDI bean for each JSF page. And let's say that i have a menu, and when it's clicked, this will lead to page A, and

问题 I'm creating a simple menuing composite component in JSF 2. However, I am unable to pass a String attribute into the composite component to use in the action attribute of the <h:commandLink>.

问题 I have an h:inputText and an h:message connected to it: <h:inputText id="myText" value="#{myController.myText}" /> <a4j:outputPanel> <h:message for="myText" .../> </a4j:outputPanel> I want to send a message to it from java, in a manner like: FacesContext.getCurrentInstance().addMessage(arg0, arg1); which is sent to h:messages, but to a specific id in a specific form.

问题 I am using jsf 2.0 and I have two bean Navigation (Application Scope ) and Module (Request Scope). I want to use methods of Navigation bean in Module Bean. I am doing in this way In Module Bean @ManagedProperty(value = "#{navigationBean}") private NavigationBean navigationBean; But when I am trying to get navigationBean.SomeMethod it is not working as navigation bean is null . How to do this? 回答1: The both beans needs to be a fullworthy @ManagedBean . The acceptor should have a public setter

问题 I have a question surrounding faces navigation. So I have a page that takes a request parameter to load a specific user. This page displays a list of commandLink that, when clicked, redirect to another page using implicit navigation. The user is loaded by calling a method in a "preRenderView". The page that we redirect to also takes a request parameter to determine which case to load. The page is also using a preRenderView. Both pages have beans that are view scoped. This all works awesome
