We will migrate the JBOSS-EAP-4 server to the JBOSS-EAP-7, using the JBOSS-EAP-4 the implementation of the Ajaxlistener class behaves smoothly, when migrating to the JBOSS-EAP-7.2 the implementation of the same class accuses Nullpointerexception. I can’t figure out why.
public class AjaxListener implements PhaseListener {
/**
* Classe Listener para interceptar todas as requisições Ajax e recarregar o javaScript da tela atualizada.
*/
private static final long serialVersionUID = 6L;
/* (non-Javadoc)
* @see javax.faces.event.PhaseListener#afterPhase(javax.faces.event.PhaseEvent)
*/
@Override
public void afterPhase(PhaseEvent pEvento) {
// Nenhuma acao a ser executada nesse callback
}
/* (non-Javadoc)
* @see javax.faces.event.PhaseListener#beforePhase(javax.faces.event.PhaseEvent)
*/
@Override
public void beforePhase(PhaseEvent pEvento) {
HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
boolean ajaxRequest = SicrdConstantes.PARTIAL_AJAX.equals(request.getHeader(SicrdConstantes.FACES_REQUEST));
if (ajaxRequest) {
OmniPartialViewContext requestContext = (OmniPartialViewContext) FacesContext.getCurrentInstance().getAttributes().get("org.omnifaces.context.OmniPartialViewFactory");
requestContext.addCallbackScript("onRenderAjax();");
}
}
/* (non-Javadoc)
* @see javax.faces.event.PhaseListener#getPhaseId()
*/
@Override
public PhaseId getPhaseId() {
return PhaseId.RESTORE_VIEW;
}
}
