Use tab, click or double click on PrimeFaces navigation available for editing. Datatable

Basically, I would like to enable the keyboard key and click on a PrimeFaces 4.0 data cell.

The issue has been reported as PrimeFaces issue 6310 , however the solution provided via demo labs appears to be no longer demo labs

<p:remoteCommand name="newRow" update="Tbl"  id="rmC"/>

<p:dataTable value="${emps}" widgetVar="wTblempl"
             var="emp" id="Tbl" filterEvent="keydown"
             editable="true" editMode="cell" rowIndexVar="rowIndex"
             scrollHeight="120" scrollable="true">

            </f:facet>

</p:dataTable>

      

        
        
        
      

    

Update:

I need to add a line that works, but when I enter it loses focus ...

public void addRow(CellEditEvent event) {

    log.info("1 add");
    int r = event.getRowIndex();

    RequestContext context = RequestContextHolder.getRequestContext();
    List<Employee> list = (List<Employee>) context.getConversationScope().get("emp");

    if (list.size() == 1 || (r + 1) == list.size()) {

      ((List<Employee>) context.getConversationScope().get("emp")).add(new Employee());

    }
    log.info("added");
}

      

        
        
        
      

    

Update 2:

I need to click on the first cell of a row, type (work), then move to the next cell (working), but immediately lose focus at once with all subsequent clicks or tabs if I don't refresh (F5) the page
