primefaces 的 p:rowEditor 用法

public void rowEdit(RowEditEvent ev) { 
		SettlementDocumentItemDetail obj = null; 
        try { 
            obj = (SettlementDocumentItemDetail) ev.getObject(); 
//            settlementIrisDetailService.updateItemDetail(obj);
            FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_WARN, "Edit Called", obj.toString())); 
        } catch (Exception ex) { 
            FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, "Error !", ex.toString())); 
            FacesContext.getCurrentInstance().validationFailed(); 
        } 
    }
