List within a List

Question

What is the most efficient way of constructing a dataTable that has a List? For Example I need to construct this table (Order List):
Order #   Products   Quantity  Status
12321     prod1         10     open
          prod2         5        
          prod3         1          
45681     prodA         7       closed
          prodB         11 Basically the orderList returns a List of Orders. Each Order has a List of Products that has to be shown. I could use a dataTable for each Products and Quantity column but I would would like to know a much cleaner/faster way
Thank you

Answer 1

You can just nest datatables.
Also see http://balusc.xs4all.nl/srv/dev-jep-dat.html � http://balusc.xs4all.nl/srv/dev-jep-dat.html#NestingDatatables
Basic example:
Order.javapublic class Order {
    private Long id;
    private List<Product> products;
    private String status;
    // + getters + setters
}Product.javapublic class Product {
    private String name;
    private Integer quantity;
    // + getters + setters
}JSF<h:dataTable value="#{myBean.orders}" var="order">
    <h:column><h:outputText value="#{order.id}" /></h:column>
    <h:column>
        <h:dataTable value="#{order.products}" var="product">
            <h:column><h:outputText value="#{product.name}" /></h:column>
            <h:column><h:outputText value="#{product.quantity}" /></h:column>
        </h:dataTable>
    </h:column>
    <h:column><h:outputText value="#{order.status}" /></h:column>
</h:dataTable>
