i want original EL of #{backingBean[property]}

In the validation phase, when i use valueBinding.getExpressionString(), It will give me "#{backingBean[property]}". But i want the original EL of jsf. Thus, how to get it back?

<ui:composition>

<h:outputLabel for="#{property}" value="#{label}" />

<h:panelGroup>

<t:inputSecret id="#{property}" value="#{backingBean[property]}" required="true" >

<f:validator validatorId="annotation" />

<a4j:support reRender="#{property}msg" event="onblur" ajaxSingle="true"

bypassUpdates="true" />

</t:inputSecret>

<t:div id="#{property}msgdiv">

<h:message id="#{property}msg" for="#{property}" errorClass="error"

fatalClass="error" />

</t:div>

</h:panelGroup>

</ui:composition>
