Listener method problem

[PATRICIA GUEDES]

Hi, everyone!!

Anyone knows why my listener method (remessaBean.delEmbque) is called twice?

<x:dataTable value="#{remessaBean.valuesEmbque}" var="values" width="760"
                 cellpadding="0" cellspacing="1"
rowClasses="inputFields" headerClass="fields">
        <x:column>
            <f:facet name="header">
                <h:outputText value="Excluir" styleClass="forms"/>
            </f:facet>
            <h:commandButton actionListener="#{remessaBean.delEmbque}"
style="cursor:hand;vertical-align:middle;"
image="/eServices/eservices/images/trash.gif" />
        </x:column>
    </x:dataTable>


public void delEmbque(ActionEvent e) {

      int index = valuesEmbqueModel.getRowIndex();
      ArrayList currentValues = (ArrayList) valuesEmbqueModel.getWrappedData();
      currentValues.remove(index);

      valuesEmbqueModel.setWrappedData(currentValues);
  }

Thanks.
