how to get old value for edit page

[oft sky]

hi, i have a datatable(usertable.jsp) to show all users-information, now i want to edit one of the users.
i can now send die user-id to beans and build the user-object and also can navigate to the userEdit.jsp .
but i do not know , how to send the user-object to the userEdit.jsp as default value,
can you give me some informations?

in view:

<h:dataTable>
  ...
  <h:commandLink actionListener="#{backing_bean.editUser}"/>
  ...
</h:dataTable>

in the backing bean:

public void editUser(ActionEvent ev) {
  UIData dataTable = findPatentHtmlDataTable(ev.getComponent());
  User user = (User)dataTable.getRowData();
}
 
private HtmlDataTable findParentHtmlDataTable(UIComponent component) {
  if(component == null)
    return null;
  if(component instanceof HtmlDataTable)
    return (HtmlDataTable)component;
  return findParentHtmlDataTable(component.getParent());
}

the important method is getRowData() which will return you the object you were at when you clicked the row but make sure the list values you provide for the dataTable are of type User, say an ArrayList of "User"s.
