Error trying to add composite component programmatically ("no tag was defined for name")

Error trying to add composite component programmatically ("no tag was defined for name") - jsf

I'm facing one of those errors that you're almost sure that you're not doing anything wrong, but the error simply won't go away, no mather what you do.
I have this composite component:
inputMask.xhtml
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:composite="http://xmlns.jcp.org/jsf/composite"
xmlns:f="http://xmlns.jcp.org/jsf/core"
xmlns:h="http://xmlns.jcp.org/jsf/html"
xmlns:c="http://xmlns.jcp.org/jsp/jstl/core">
<composite:interface>
<composite:attribute name="value" />
<composite:attribute name="mask" type="java.lang.String" required="true" />
<composite:attribute name="converterId" type="java.lang.String" default="br.edu.ufca.eventos.visao.inputmask.inputMask" />
</composite:interface>
<composite:implementation>
<h:outputScript library="script" name="inputmask.js" target="head" />
<h:inputText id="mascara">
<c:if test="#{cc.getValueExpression('value') != null}">
<f:attribute name="value" value="#{cc.attrs.value}" />
</c:if>
<f:converter converterId="#{cc.attrs.converterId}" />
<f:attribute name="mask" value="#{cc.attrs.mask}" />
</h:inputText>
<h:outputScript target="body">
defineMask("#{cc.clientId}", "#{cc.attrs.mask}");
</h:outputScript>
</composite:implementation>
</html>
When I use it in a xhtml page like this:
<ui:composition template="layout.xhtml"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
xmlns:ec="http://xmlns.jcp.org/jsf/composite/componente">
<ui:define name="contents">
<ec:inputMask value="#{bean.cpf}" mask="999.999.999-99" />
</ui:define>
</ui:composition>
Everything works fine. The component is rendered without problems and works well.
But when I try to add it programmatically, using OmniFaces Components#includeCompositeComponent, like this:
Map<String, String> attributes = new HashMap<>();
attributes.put("mask", "999.999.999-99");
Components.includeCompositeComponent(Components.getCurrentForm(), "componente", "inputMask.xhtml", "a123", attributes);
I get this error:
javax.faces.view.facelets.TagException: //C:/wildfly-10/standalone/tmp/eventos.ear.visao.war/mojarra7308315477323852505.tmp #2,127 <j:inputMask.xhtml> Tag Library supports namespace: http://xmlns.jcp.org/jsf/composite/componente, but no tag was defined for name: inputMask.xhtml

I would like to have your help to solve this issue, because I've already tried many things but didn't have success.
I'm using Wildfly 10.1.0.Final (which comes with Mojarra 2.2.13)
PS.: I know Primefaces has an input mask component, but I wouldn't like to use Primefaces.
---- UPDATE ----
If I change the code to add the composite component to this (changing inputMask.xhtml to just inputMask):
Components.includeCompositeComponent(Components.getCurrentForm(), "componente", "inputMask", "a123", attributes);
I get this error instead:

We're currently porting our GlassFish 3.2.1.x webapp to JBoss EAP 6.4.6, but we're getting a rather strange exception with a page that contains (shortened):

The <ui:include src="absenceSubPanel.xhtml" /> contains the <o:validateMultiple>'s components. It's the sub panel for an absence (e.g. vacation, sickness, some educational measure for an employee).
The remarks are conditional depending on some customer setting whether they have absences with or without mandatory remarks.

OmniFaces version is 1.7. We're also using PrimeFaces 3.5.28 (the last of the 3.5 tree) and Seam Faces 3.2.0.
Any ideas what could cause this and how to fix it?
Thanks

We have just been able to get rid of the exception by putting the following into the faces-config.xml file:
<component>
<component-type>org.omnifaces.component.validator.ValidateMultiple</component-type>
<component-class>org.omnifaces.component.validator.ValidateMultiple</component-class>
</component>
Is there any explanation/assumption for why this is the remedy?

h:selectOneMenu without value in composite component throws nullpointerexception

I have a selectOneMenu in a composite component like this:
<!-- INTERFACE -->
<cc:interface>
<cc:attribute name="label"/>
<cc:attribute name="value"/>
</cc:interface>
<!-- IMPLEMENTATION -->
<cc:implementation>
<h:outputLabel value="#{cc.attrs.label}" for="input"/>
<h:selectOneMenu id="input" value="#{cc.attrs.value}" styleClass="width100">
</h:selectOneMenu>
<h:message id="#{cc.attrs.id}-message" for="input" />
</cc:implementation>
If I don't specify a value attribute when using this component:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"

<p:commandButton value="Save" />
</h:form>
</h:body>
</f:view>
</html>
I get a nullpointerexception when submitting the form.:

I use jsf 2.2 (with Wildfly 9.0.1). If I use an inputText instead of a selectOneMenu it works well. It does not depend on the select not having options (it is not obvious from this example, but my original more complex one proved it), it defnitely depends on the selectOneMenu having an empty value attribute. It also works well if I specify a value, so it is not a huge problem, but makes things a bit more uncomfortable during development. Do you have any idea why it happens? Any solution, workaround? Thanks.

Primefaces: DataTable inside AccordionPanel throws NullPointerException

I have a Primefaces DataTable inside an AccordionPanel with dynamic number of tabs. The DataTable can be sorted by each column by click on the column header.
The DataTable throws an NullPointerException in Primefaces' DataTable class when updating a row. The error occurs only after the table has been sorted before.
I've tested the same table outside the accordion, and it does not show the error.
What am I doing wrong ?
My xhtml:

PrimeFaces 5.1.14, Omnifaces 2.0, WildFly 8.2.0

The solution is to use widgetVar="data" inside datatable.
Is necessary to Javascript recognize this ID.
<p:dataTable width="100%" var="wearData" value="#{wearDataBean.getWearData(type)}" sortBy="#{wearData.aggregate.sequence}" sortOrder="ASCENDING"
scrollable="false" rowStyleClass="" styleClass="" emptyMessage="#{messages['lbl.no.data']}" widgetVar="data">
Intro To PrimeFaces widgetVar

I had the same problem regarding the sorting of datatables dynamically generated in tabs from accordionPanel and the widgetVar solution didn't fix my issue.
The solution that made the sorting work was to include a p:columnGroup(not so useful besides making things work)
<p:columnGroup type="header">
<p:row>
<p:column headerText="Column 1">...</p:column>
...
</p:row>
</p:columnGroup>

Thanks in advance.

JSF: EvaluationException and NPE when method in a #ViewScoped bean is called

fellow Java warriors!
I have this managed bean to handle the Rede (Network) entity related operations called RedesBean (NetworksBean). I have three pages to insert a new network: redes/nova.xhtml (new.xhtml), which is basically a series of input fields to insert the Network properties and a commandButton which invokes a cadastraNova() (createNew()) method which validates the input and calculates some values. The cadastraNova() method then returns to another page, redes/confirma.xhtml (confirm.xhtml) which shows the value of each property and the calculated values, asks for user confirmation and then invokes another method, cadastraRede() (createNetwork()) to persist the Network to database via JPA.
When I use #RequestScoped, the values are not preserved between the second and third views. When I use #SessionScoped, the values are preserved, but I think #SessionScoped-ing this is a bit too much. So, after a bit of Googling, I found this #ViewScoped annotation which I think fits perfectly to my case. But here's the issue: after I click the commandButton in the first view (redes/nova.xhtml), I get a NullPointerExcetption, caused by a EvaluationException. The cadastraNova() method is invoked, but it fails to evaluate the bean property values. The relevant code is posted below:
RedesBean.java
package br.cefetmg.ccc.gerir.web;
// suppressed imports
/**
* Bean to manage network and subnetwork views
* #author Arthur Alkmim
*
*/
#ManagedBean(name="redes")
#ViewScoped
public class RedesBean implements Serializable{
#EJB
transient RedeDAO redeDAO;
private static final Logger logger = Logger.getLogger("br.cefetmg.ccc.gerir.web.RedesBean");
// attributes, suppressed
// getters and setters, suppressed
// the "broken" method
public String cadastraNova(){
logger.info("Method cadastraNova() successfully invoked");
// verifica se a rede não já existe
if(redeDAO.buscaPorId(ipBase) != null){
FacesContext.getCurrentInstance().addMessage("Rede já existente", new FacesMessage("Já existe uma rede com esse IP"));
return FacesContext.getCurrentInstance().getViewRoot().getViewId();
}
calculaAtributos();
// verifica se o range de lease é válido
if(!validaRange())
// volta para a página de cadastro
return FacesContext.getCurrentInstance().getViewRoot().getViewId();
return "/redes/confirma";
}
// other suppressed methods
}

So, as you guys can see, the method is really being invoked by the logger output in the log first line. The method fails when it evaluates a property which is probably not being updated. So, how to fix?

The only which can be null in the method snippet you've shown as far is redeDAO. Since it's marked transient I think that the server is configured to store views/sessions on disk immediately (by serialization) instead of being kept in memory all the time. Anything which is declared transient will be lost during serialization and JSF can't reinject it for you after deserialization.
I'd suggest to make the #EJB non-transient (just implement Serializable) and retry.

Kind of solved it. I changed from #ViewScoped to #ConversationScoped and used CDI annotations instead of JSF ones - that is, #Named and #Inject instead of #ManagedBean and #EJB.
