问题 Unfortunately, primefaces accordionPanel doesn't works well in version 2.2.1 if you are trying to create tabs dynamically. This is my case, I need to create accordions if the user clicks an add icon, and remove if he clicks on x icon. No problem, I've created my own composite component, like you can see here: <c:interface> <c:attribute name="titulo" default="" required="false" /> <c:attribute name="renderizar" default="true" required="false" /> <c:attribute name="width" required="false"

libraries for JSF (Sun/Oracle Mojarra)

由 六月ゝ 毕业季﹏ 提交于 2019-12-29 07:48:15
问题 I am downloading Sun/Oracle Mojarra implementation of JSF from http://javaserverfaces.java.net/download.html I downloaded the latest -2.1.9 binary. It comes with only one jar - javax.faces-2.1.9.jar. I had a sample project which I believe is using the older 2.0 version, which includes 2 jars - jsf-api.jar and jsf-impl.jar. I replaced those 2 older jars with the single new jar. It seems like the sample project still works well. My question: Is there anything else I need to do besides replacing

Illegal Syntax for Set Operation: How to tell JSF I don't “want” a setter

由 ε祈祈猫儿з 提交于 2019-12-29 06:52:26
问题 This question may be more of the type "conceptual" or "I don't understand JSF". My scenario: I have a JSF Page ( index.xhtml ) where I use a p:accordionPanel (but I don't think it matters what component it is). What I want to do is to set the activeIndexes of it. <p:accordionPanel multiple="true" activeIndex="#{myController.getActiveIndexesForSections('whatever')}"> // bla bla... </p:accordionPanel> And the (simplified) method in the backing bean: public String getActiveIndexesForSections

How to display value of List#size() in JSF EL?

由 爱⌒轻易说出口 提交于 2019-12-29 05:43:05
问题 I'd like to know if there's a way to bind the returned value of a method into a JSF component. I'll explain myself better. Let's say I have a class like this: public class Document { private List<Attachment> attachments; //getter and setter here } this class is exposed to jsf through a registered managed bean in a property called currentDocument, and used in a jsf this way <h:outputText value="#{myManagedBean.currentDocument.attachment.size}" /> This isn't correct, I know. But what is the

How does JSF find beans annotated with @ManagedBean?

由 亡梦爱人 提交于 2019-12-29 03:31:07
问题 As far as I know, for using @Annotations (or [Attributes] in C#) you have to have a reference to the class metadata, so that you can ask if the class is annotated (attributed) or not. My question is how does JSF implementation find all classes annotated with @ManagedBean? Does it scan all of the classes in the class path? Or is there a way to actually "query" the JVM for the annotated classes? I'm asking this because when I put my annotated backing beans in my web project directly, there's no

JSF 2.0: use Enum values for selectOneMenu [duplicate]

问题 This question already has answers here : How to use enum values in f:selectItem(s) (4 answers) Closed 4 years ago . I'm using JSF 2.0 and want to fill a selectOneMenu with the values of my Enum.

Using bootstrap related tags inside JSF2 h:inputText component

由 好久不见. 提交于 2019-12-29 01:53:13
问题 Is there anyway to use bootstrap related tags in JSF2 components? For example I'm interested in using the bootstrap typeahead feature which requires something like <h:inputText id="typeahead" type="text" data-provide="typeahead"></h:inputText> but since data-provide doesn't exist for h:inputText it gets stripped out and so the typeahead feature would obviously not work. 回答1: Depends on JSF version you're using. In JSF 2.0/2.1 , it's not possible to specify additional attributes. The JSF HTML
