javax.faces.FacesException：式のエラー：名前付きオブジェクト：org.omnifaces.component.validator.ValidateMultiple

Question

を見つけていない私たちは現在、のJBoss EAP 6.4.6、に私たちののGlassFish 3.2.1.x Webアプリケーションを移植していますしかし、我々は含まれているページ（短縮）とかなり奇妙な例外を取得している：

<h:panelGroup id="absence-panel" 
       layout="block" 
       styleClass="bx-accordion-correction"> 

    <h:panelGroup layout="block" 
        styleClass="left-button-panel"> 
     <p:commandButton id="add-absence-btn" 
         icon="ui-icon ui-icon-document" 
         value="#{msg['common.action.add.label']}" 
         actionListener="#{employeeAbsenceManager.add}" 
         immediate="true" 
         process="@this" 
         update="absence-panel 
           :content-form:employee-navigation 
           :content-form:msgs 
           :content-form:growl" 
         oncomplete="scrollContentToSubPanel(this);" 
         disabled="#{employeeManager.readOnly or employeeAbsenceManager.mode eq 'ADD' or employeeAbsenceManager.mode eq 'EDIT'}" 
         styleClass="bx-first-button"> 
      <p:resetInput target=":content-form:accor-panel:absence-subpanel" /> 
     </p:commandButton> 
    </h:panelGroup> 

    <p:blockUI block="absence-dir-list" 
       blocked="#{employeeAbsenceManager.mode eq 'ADD' or employeeAbsenceManager.mode eq 'EDIT'}" /> 

    <p:dataTable id="absence-dir-list" 
       value="#{employeeAbsenceManager.dataModel}" 
       var="abs" 
       selection="#{employeeAbsenceManager.selectedEntity}" 
       selectionMode="single" 
       resizableColumns="true" 
       rowKey="#{abs.timestampId}" 
       rowStyleClass="#{abs eq employeeAbsenceManager.selectedEntity ? 'ui-state-highlight' : null}" 
       paginator="true" 
       paginatorPosition="bottom" 
       rows="10" 
       rowsPerPageTemplate="10,20" 
       paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}" 
       emptyMessage="#{employeeAbsenceManager.activeOnly ? msg['entity.absence.list.emptyMessageActive'] : msg['entity.absence.list.emptyMessage']}" 
       styleClass="bx-datatable-header-hidden mt-10px datatable-content-scrolling max-width-1300"> 
     ... 
    </p:dataTable> 

    <ui:include src="absenceSubPanel.xhtml" /> 

    <h:panelGroup id="absences-validator"> 
     <o:validateMultiple components="absence-type absence-begin-date #{employeeAbsenceManager.uniqueConstraintWithRemarks ? 'absence-remarks' : ''}" 
          validator="#{employeeAbsenceManager.validateUniqueAbsences}" 
          message="#{employeeAbsenceManager.uniqueConstraintWithRemarks ? 
             msg['entity.absence.notUniqueMessageWithRemarks'] : 
             msg['entity.absence.notUniqueMessageWithoutRemarks']}" /> 
    </h:panelGroup> 
</h:panelGroup> 

<ui:include src="absenceSubPanel.xhtml" />は<o:validateMultiple>のコンポーネントが含まれています。これは、休暇（例えば、休暇、病気、従業員のための教育措置）のサブパネルです。

備考は、顧客の設定に応じて、の有無にかかわらず欠席しているかどうかに応じて条件付きです。備考。

我々は、次の例外を取得：

OmniFacesのバージョンは1.7です。また、PrimeFaces 3.5.28（3.5ツリーの最後）とSeam Faces 3.2.0も使用しています。

何が原因で発生する可能性があり、修正する方法はありますか？私達はちょうどfaces-config.xmlファイルに次のように置くことによって、例外を取り除くことができました

おかげ

Answer 1

：

<component> 
    <component-type>org.omnifaces.component.validator.ValidateMultiple</component-type> 
    <component-class>org.omnifaces.component.validator.ValidateMultiple</component-class> 
</component> 

これは救済策である理由のために任意の説明/仮定がありますか？
