title: Display formatted decimal numbers in Primefaces 4
body: <p>I have a database table with a float field and I want to display it through Primefaces.
  I want to display the numbers formatted as (one thousand, for example): 1.000,00
  I tried:</p>
  
  <pre><code>&lt;p:column sortBy="#{item.value}" filterBy="#{item.value}"&gt;
    &lt;f:facet name="header"&gt;
      &lt;h:outputText value="#{epoBundle.ListUpbTitle_value}"/&gt;
    &lt;/f:facet&gt;
  &lt;h:outputText value="#{item.value}"/&gt;
  &lt;f:convertNumber pattern="#0.000" locale="pt_BR"/&gt;
  &lt;/p:column&gt;
  </code></pre>
  
  <p>But got:
      /WEB-INF/include/entity/upb/List.xhtml @80,55 <strong> Parent not an instance of ValueHolder: org.primefaces.component.column.Column</strong>@13ec99d0</p>
  
  <p>Can someone help me?</p>
  
  <p>Thanks in advance.</p>
