JSF access to the "var" attribute value from dataTable from jsp - jsf

Question

I'm using JSF 1.1. I have a JSP page with a
....
<t:dataTable id="data"
styleClass="scrollerTable"
headerClass="standardTable_Header"
footerClass="standardTable_Header"
columnClasses="col1,col2,col3"
var="product"
value="#{beanProduct.listOfProducts}"
preserveDataModel="false"
rows="10"
>
....
The #{product} has a attribute named state. If its value is "pending", then I want to display a <h:commandButton>, else I display nothing.
How can I get the value of #{product.state} in JSP scriptlet code?
I tried the next:
....
<h:column>
<f:facet name="header">
<h:outputText value="#{messages['list']}" />
</f:facet>
<%
// ----> In this point, I want know the value of "product.state"
FacesContext context = FacesContext.getCurrentInstance();
Application app = context.getApplication();
ValueBinding binding = app.createValueBinding("#{product.state}");
Object valueOfProduct = binding.getValue(context);
String stateProduct = (String)valueOfProduct;
if (stateProduct.equals("pending")) {
%>
<h:panelGrid>
<h:commandButton value="Send" actionListener="#{beanProduct.Item}" action="#{beanProduct.sending">
<f:attribute name="idProduct" value="#{product.id}" />
</h:commandButton>
</h:panelGrid>
<%
}
else {
%>
// Do nothing.
<%
}
%>
</h:column>
</t:dataTable>
But it does not work. How can I achieve this?

You should use "rendered" attribute instead:
<h:column>
<f:facet name="header">
<h:outputText value="#{messages['list']}" />
</f:facet>
<h:commandButton rendered="#{product.pending}" value="Send"
actionListener="#{beanProduct.Item}"
action="#{beanProduct.sending">
<f:attribute name="idProduct" value="#{product.id}" />
</h:commandButton>
</h:column>
Mixing JSF and JSP like this won't work because dataTable var will not be available at the time your embedded code is executed. Also it is not a recommended practice.
