I think you wanna send  parameter to action  to delete a person in your sample, but in correct way you should send an object like 'person entity' to delete it.
so, in this tag '<f:param name="selectpersonalid" value="#{items.persinalid}"/>
you shuold implement like it :

FacesContext facesContext = FacesContext.getCurrentInstance();

if(facesContext == null) {
   System.out.println("facesContext is null");
} else {
   String id = (String) facesContext.getExternalContext().getRequestParameterMap().get("selectpersonalid");
}
and the best practice is use SEAM Framework and it's Annotations, like this :

@RequestParameter("selectpersonalid")
private String selectpersonalid;
