问题 I am facing problems with dialog windows validation. On home.xhtml I have a tabview with 3 nested dataTables and CRUD buttons (see screenshot). Every button is supposed to call a dialog window with a form to add/edit entity. But whenever I fail to validate some field in any form - all other forms are displayed too: I would like to validate and display only one dialog at a time and keep it displayed untill user presses "Cancel" button or inputs valid values and presses submit button. No other

问题 I have JSF and PrimeFaces 3.5 web application. Page home.xhtml contains a tabView component with 3 nested dataTables and buttons that perform add/edit/delete operations. Every button calls a p:dialog with different form. Whenever one of the dialogs get validation error, all other dialogs are displayed too because their attribute is visible="#{facesContext.validationFailed}" (IMHO) I need to display only one dialog which failed to validate untill user enters valid values or presses Cancel

问题 I see, that in JSF most of the standard components that mapped to HTML tags, e.g. <h:commandButton/> , have attributes class and styleClass . But no matter, which one I use, both is rendered as class attributes in markup. So why there are two attributes with the same purpose? 回答1: There is simply no class attribute in JSF components. From the doc, attribute styleClass : Space-separated list of CSS style class(es) to be applied when this element is rendered. This value must be passed through

问题 I've got a problem with using p:ajax update atribute element. When I use in my code <p:ajax update="@all" /> then I am getting javax.el.PropertyNotFoundException . When I use <f:ajax render="@all" /> I don't get any. I though that thouse tags are nearly same. Can anyone explain whats happening? I am using mojjara implementation, primefaces 3.5 and Liferay jsf portlet bridge. Example of stacktrace: Caused by: javax.el.PropertyNotFoundException: /pages/views/personForm.xhtml @95,99 value="#

问题 I am facing the duplicate ids for columns issue in p:treeTable i.e. same problem as described in the below link http://forum.primefaces.org/viewtopic.php?f=3&t=31158&p=99463#p99463 So I would like to implement the solution as suggested in the above solution. So I thought of changing the source code and recompile and use the jar but I haven't got permission to do the same. I was asked to customise the class by extending the org.primefaces.component.api.UITree class or somehow without changing

问题 I'm using a SessionFilter servlet for validating users and then giving access of the system to them. My restricted files are in a folder named "com.shadibandhan.Restricted". Session filter is working fine. here's the relevant code of the sessionfilter servlet @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest) req; HttpServletResponse response = (HttpServletResponse)

问题 As I was experimenting with JSF 2.0 , i came across a scenario like this . I have two text fields - based on input of first field an ajax call is fired using <f:ajax ... /> After the response is back I am re rendering the second text field ..but i want to disable the second text field based on some server side validation of first field value. I don't want to set the disabled using style based on a third property which is being set in the bean after validation. Is there any alternative ways..

问题 CDI newbie question. Simple test scenario: JSF + CDI SessionScoped beans. I need an elegant way to instantiate a known set of session scoped CDI beans without mentioning them on a JSF page or calling their methods from other beans. As a test case - a simple logging bean, which simply logs start and end time of an http session. Sure, I could create an empty JSF component, place it inside of a site-wide template and make it trigger dummy methods of the required session beans, but it's kinda

问题 I have a @ViewScoped -annotated managedbean whose @PostContruct -method fetches a list from database to be displayed in a table in the view. Now when I delete an item I want the changes to be seen in the view. To keep this dynamic and reusable I only want to delete from database (not manually from list). So I need to destroy/recreate the bean I suppose. Now I do this by navigating to the same view. But the way I do is not reusable. Can I just destroy the bean manually or navigate to the same

问题 I've already asked this question on the Icefaces forum, but meanwhile I realized that this is a more generic problem. I'd like to update parts of a JSF page when I get a message in my MDB. The problem is, how do I get the FacesContext from the EJB container? In the message processing function FacesContext.getCurrentInstance() returns null. I've also tried to make a JSF managed bean be a MDB, but I couldn't (it seems you can't have both in the same class?). Since I'm a beginner in the JSF
