Display key and value Map in primefaces datatable

In my Java EE 6 / JSF 2 project I have a Map property advantages in the Employee entity: 

@ElementCollection
private Map<String, Float> advantages;

The key represents the advantage name and the value represents the cost associated with the advantage name. This is mapped to a table with three columns Employee_Id, Advantages and Advantages_Key. I need to display all map entries in my <p:dataTable> which shows a List<Employee>. How can I achieve this?

this works for me, and this is my map in bean Map:

<p:dataTable id="dtbAddedRoles" value="#{controllerUserCreationMain.mapUtil.entrySet().toArray()}"
                                var="roleAdded">
                                <p:column headerText="Role">
                                    <p:outputLabel value="#{roleAdded.key.roleName}" />
                                </p:column>
                            </p:dataTable>

I know that answer is too late, but maybe for others it will be useful.

Assume your haspmap is defined as follows:

HashMap<String, BigDecimal> myHashMap;

public List<Entry<String, BigDecimal>> getMyHashMapEntryList() {
return new ArrayList(myHashMap.entrySet());
}

in your UI:

<p:dataTable value="#{yourBean.myHashMapEntryList}" var="myEntry">
    in here reference as: #{myEntry.key} #{myEntry.value}
</p:dataTable>

Provided that your environment supports EL 2.2 (Java EE 6 does), and that #{employee} in the below example is coming from <p:dataTable var>, then this should do

<ui:repeat value="#{employee.advantages.entrySet().toArray()}" var="entry">
    Name: #{entry.key}, Cost: #{entry.value}
</ui:repeat>
