Question

I have a dataTable filled with information. On selected one rown “onRowSelect” method is called.
“Order number ” outputText entry is populated with value retrieved from ProductOrder object.

/* Filter bean */
public void onRowSelect(SelectEvent event) {
    NewOrderBean currentOrder = (NewOrderBean) FacesUtils
            .getManagedBean("newOrderBean");
    currentOrder.setOrderNum(((ProductOrder) event.getObject()).getOrderNum());
}

/* newOrderBean */
public int update() {
    ProductOrder pt = new ProductOrder ();
    try {
        pt = productService.findOrderbyNum(orderNum).get(0);
    } catch (Exception e) {
        return 0;
    }

    pt.setOrderNum(orderNum);

    try {
        FacesMessage msg = new FacesMessage("Product updated with: ", orderNum);
        FacesContext.getCurrentInstance().addMessage(null, msg);
        return 1;
    } catch (Exception e) {
        return 0;
    }
}

User, after entering new text into “Order number “, presses Update to modify product order number.

<!-- JSF page -->

    <h:form class="ViewResservation" id="viewPanel">
        <p:tabView id="tabView">
            <p:tab title="Client" id="tab1">
                    <h:outputText value="Order number " />
                <p:inputText id="ordr" value="#{newOrderBean.orderNum}" />
                </p:tab>
            </p:tabView>    
    </h:form>
</ui:define>        
    <ui:define name="footer">
        <h:form>
            <h:commandButton value="Update"
                actionListener="#{newOrderBean.update}" />
        </h:form>
    </ui:define>

Problem is that after entering new text and pressing Update, value (orderNum) stays the same. How can I get value enterted by user and
update ProductOrder object with new order number?

Answer 1

The tab must be inside the tabview element. You have it inverted.

For your problem, your order number is set in one form and your submit button in another. You need to put both in the same form else the order number isn’t submitted.
