Displaying Hashmap keys and values in a primefaces DataTable

Question

I\'m trying to display a Hashmap in a DataTable, here\'s what i\'m trying to do : I\'ll have a select menu of some products, and an input text for quantity, an \"ajaxified\"

Answer 1

You create Class like this:

public class Product{
    private int id;
    private String productName;
    private int quantitiy;

    // add getters setters here
}

// add product id to map key
Map myMap = new HashMap();

public Map getProductMap() {
   return myMap;
}


public List getProducts() {
   return new ArrayList(myMap.values()_;
}

Add datatable value to getProducts() List

Otherwise, product as a map key then,

Map myMap = new HashMap();

public List> getProducts() {
    Set> productSet = 
                     myMap.entrySet();
    return new ArrayList>(productSet);
}

write primeface page like this way,
