I am study about primeface and i follow code sample at http://www.primefaces.org/showcase/mobi ... acts.xhtml
but i have problem about when use properties update=" form "
javax.faces.FacesException: Cannot find component with expression ":editForm:editFormPanel" referenced from "list:j_idt6".
i don't know why Cannot find component id "editForm"
How can I use exactly properties update=":editForm:editFormPanel"
Code: Select all
<pm:header title="Contacts" swatch="b">
<p:commandButton styleClass="ui-btn-right ui-btn-inline" value="New" icon="ui-icon-plus" update=":editForm:editFormPanel" action="#{contactsView.prepareNewContact}"/>
