Displaying Map object fields in DataTable

Question

I am trying to create a shopping cart app. The ShopCart bean has a Map property:
Map shoppingItems = new Hashtable();In addition to the getter setter method, the bean has a addShoppingItem() method that adds a Product object to the Map.
public void addShoppingItem(String index,Product item)
         shoppingItems.put(index,item);                 
       }The Product class has fields, such as id, name, price and getter/setter methods. The index argument passed to addShoppingItem() is the id field of the value of the Product object.
I am now desperately trying to display information of all Product objects added to the Map in a datatable.
Is this possible? Please help.

Answer 1

It should be possible - you will need something like
JSP/JSF code
<h:dataTable id="cart"
value="#{shoppingCart.products}"
var="product" first="0" >
<h:column >
<f:facet name="header">
<h:outputText value="product code" />
</f:facet>
<h:inputText id="productCode" value="#{id}" />
</h:column>
In your Backing bean code you will need a
Map getProducts() method
NOT the above definetely works whenreturning a List
I have seen people say it also works with a Map - but haven't tried it myself - so am not 100% sure
