  <p>I'm using selectManyCheckbox here:</p>
  
  <pre><code>&lt;html xmlns="http://www.w3.org/1999/xhtml"
  xmlns:ui="http://java.sun.com/jsf/facelets"
  xmlns:h="http://java.sun.com/jsf/html"
  xmlns:f="http://java.sun.com/jsf/core"
  xmlns:t="http://myfaces.apache.org/tomahawk"&gt;
  &lt;ui:component&gt;
  &lt;h:panelGroup layout="block" styleClass="hrgi-div-form clearfix tamanho-aba-cadastro"&gt;
      &lt;t:selectManyCheckbox id="selectFuncoes" value="#{funcionario.funcoes}" layoutWidth="2"&gt;
          &lt;f:selectItems value="#{carregadorFuncoesFuncionario.itens}" /&gt;
      &lt;/t:selectManyCheckbox&gt;
  &lt;/h:panelGroup&gt;
  &lt;/ui:component&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>and configured web.xml this way:</p>
  
  <pre><code>&lt;filter&gt;
      &lt;filter-name&gt;MyFacesExtensionsFilter&lt;/filter-name&gt;
      &lt;filter-class&gt;org.apache.myfaces.webapp.filter.ExtensionsFilter&lt;/filter-class&gt;
      &lt;init-param&gt;
          &lt;param-name&gt;uploadMaxFileSize&lt;/param-name&gt;
          &lt;param-value&gt;20m&lt;/param-value&gt;
      &lt;/init-param&gt;
  &lt;/filter&gt;
  
  &lt;filter-mapping&gt;
      &lt;filter-name&gt;MyFacesExtensionsFilter&lt;/filter-name&gt;
      &lt;servlet-name&gt;Faces Servlet&lt;/servlet-name&gt;
  &lt;/filter-mapping&gt;
  
  &lt;filter-mapping&gt;
      &lt;filter-name&gt;MyFacesExtensionsFilter&lt;/filter-name&gt;
      &lt;url-pattern&gt;/faces/myFacesExtensionResource/*&lt;/url-pattern&gt;
  &lt;/filter-mapping&gt;
  </code></pre>
  
  <p>I'm using Tomahawk 1.1.11, myfaces 2.1.6 and primefaces 2.1.1
  How can I solve it?</p>
