Question

<p:dataTable id="#{id}" var="order" rowIndexVar="rowId" value="#{ordersProvider}" emptyMessage="No more rows" rowKey="#{id}" selectionMode="single">
    <p:column headerText="№" filterBy="#{order.id}" filterMatchMode="contains">

            <h:outputText value="#{order.id}"/>
        </div>

</p:dataTable>

    public void cancel(OrderBG order){

    order.setStatus(OrderStatus.Canceled);
    Environment.getInstance().getServiceProvider().getOrderBgService().save(order);
}

Answer 1

问题已由getter和setter成功解决。

在托管bean中：

private OrderBG newOrder = new OrderBG();

public OrderBG getNewOrder() {
    return newOrder;
}

public void setNewOrder(OrderBG newOrder) {
    this.newOrder = newOrder;
}

public void cancel(){

    getNewOrder().setStatus(OrderStatus.Canceled);
    Environment.getInstance().getServiceProvider().getOrderBgService().save(getNewOrder());
}

在xhtml UI中：

    <p:contextMenu for="#{id}">
    <p:menuitem value="Delete" update="#{id}" icon="ui-icon-close" actionListener="#{clientOrdersBean.cancel}"/>
</p:contextMenu>

<p:dataTable id="#{id}" var="order" value="#{ordersProvider}" emptyMessage="Заявки отсутствуют" rowKey="#{id}" selection="#{clientOrdersBean.newOrder}" selectionMode="single">
