How to Persist Rows after Reordering in backing bean

[primesieger]

I am using Primefaces Datatable to show the data, i have used draggablerows and trying to save/persist the reordering of the rows in the backing bean

with
<p:ajax event = onRowReorder listener=#{bean.onRowReorder}/>

I can get the from and to indexes from the event. But, I was not able to persist the row reordering:

<p:dataTable value="#{EmployeeHandler.model.employees}" var="employee" draggableRows="true">

<p:ajax event="rowReorder" listener="#{EmployeeHandler.onRowReorder}"/>

<p:column>
<h:outputText value="#{employee.id}"/
</p:column>
<p:column>
<h:outputText value="#{employee.firstName}"/
</p:column>

<p:column>
<h:outputText value="#{employee.lastName}"/
</p:column>
</p:dataTable>


I tried

public void onRowReorder(ReorderEvent event) {
event.getFromIndex();
event.getToIndex();
// I want to iterate through all the rows and save the new order of the employees list
}
