I'am new to PrimeFaces. I'am using it to code the front end of a Saas Application. I' am using a primefaces datatable to display a list of customers. I need to sort and filter the values. Also I need to populate another widget when a row is selected on the datatable. Sorting works but filtering and selection don't work. Below are the code snippets of the bean and the faces page. I'am using PrimeFaces 2.2.1 and JSF 2.0.2.

The code is not populating the "selectedCustomer" object in the bean.
What i Undestand from your question is you want create an Editable DataTable. As you are using dataTable attribute selectionMode="Single" which seems everything right for me. I cant say what went wrong with it as it involved many other complexities. But you can achieve the samething (populating selectedCustomer In Backing bean)
Solution1: you implement Below listener
rowEditListener="#{customerBean.listenerInBackingBean}"
And In backing bean..........
public void listenerInBackingBean(org.primefaces.event.RowEditEvent ev) {
Customer selectedCustomer = (Customer) ev.getObject();
//write Logic to Store Customer in Database
}
Solution 2:
<p:commandButton >
<f:setPropertyActionListener value="#{customer}" target="#{customerBean.selectedCustomer}" />
</p:commandButton>
Here selectedCustomer is instance of type Customer.
