Erro no Template (Struts2)

Bom dia amigos, estou tentando usar a componet do struts2 da seguinte forma:

<s:component template="data.flt" theme="meutema"> <s:param name="name" value="'dataNascimento'" /> <s:param name="label" value="'Data de Nascimento'" /> </s:component>

data.flt

${parameters.label}: <input type="text" name="$!{webwork.htmlEncode(${parameters.name})}_dia" size="5" /> / <input type="text" name="$!{webwork.htmlEncode(${parameters.name})}_mes" size="5" /> / <input type="text" name="$!{webwork.htmlEncode(${parameters.name})}_ano" size="10" />

quando executo a página dá o seguinte erro:
