如何在p：datatable中将焦点设置为特定的行/列（添加新行时为下一个单元格）？

Question

我有一个“添加”按钮，可在表格底部添加新行。这一切都很好。但是，当用户单击添加时，我想将焦点设置到表底部新行中的第一列。我该怎么做？

我尝试了以下各种语法，但是没有运气。

<p:commandButton id="addDetailButton"  value="#{bundle.Add}" actionListener="#{invoiceController.addInvoiceDetail()}"
                                           oncomplete="PrimeFaces.focus('InvoiceDetails:'+#{invoiceController.selected.invoiceDetails.size()}+':editorProductService')"
        update="InvoiceDetails"  disabled="#{invoiceController.selected.account==null}"/>

using javascript funtion 
 oncomplete="nexts('#{p:component('service')}')"
function nexts(idNext){
     element = document.getElementById(idNext);   
     $(idNext).focus();     
}


 <h:form id="InvoiceCreateForm">

我想在用户完成当前单元格的编辑时将焦点设置到下一个单元格，即使添加了下一个rew也是如此。

我没有任何错误，但是没有用。
