问题 In my backing-bean I have a collection of objects of different subclasses sharing a common interface. Inside the view, an ui:repeat iterates over this collection. Inside this loop, different properties have to be rendered depending on the concrete implementation of the interface. I reduced the problem to the following backing bean: @Named @SessionScoped public class DummyBean implements Serializable { private List<Type> objects = new ArrayList<Type>(); public void add1() { objects.add(new

I will like to edit a list of items in the same page. Each item should be edited using a separate form. I am creating a h:form within ui:repeat. Only when the last form is submitted, the user input is applied to the managed bean. For all other forms, user input is not applied to the model. @ManagedBean public class Controller { Logger logger = Logger.getLogger("TestWeb"); private List<Customer> customerList; public List<Customer> getCustomerList() { if (customerList == null) { customerList = new ArrayList<Customer>(); customerList.add(new Customer("Daffy Duck", "daffy@example.com"));

How can I set id of a component/tag inside ui:repeat

由 放肆的年华 提交于 2019-11-26 22:55:11
I'm trying to assign an id to a component inside a <ui:repeat> like that: <ui:repeat value="#{bean.columns}" var="column"> <h:panelGroup layout="block" id="column_#{column.id}" styleClass="#{column.id} dashboard_column"> The thing is that #{column.id} value is being placed properly inside the styleClass value but its not being set inside the id attribute. All that is being set inside the id attribute is the automatically generated id by the JSF + my hard coded value column_ . If I remove the hard coded column_ I get an exception: java.lang.IllegalArgumentException: component identifier must

(I could change the storage modality if the answer demands it). When the user finishes answering all

问题 I'm using com.sun.faces version 2.1.18 . In my application I have a dynamic list of questions. I use <ui:repeat> to render each question. Depending on the type of question I render a type of input component and validation. In case of a number range question I use <h:inputText> with <f:validateLongRange> . The problem I run into is that the minimum and maximum attributes on the <f:validateLongRange> are always set to the first question's minimum and maximum value. So, when you use the

问题 Using JSF 2.0, I need to display a table wherein each row contains a link which opens a popup. I have two models: A which has id and List<B> properties and B which has id and name properties.
