Question

I have this dataTable:

<h:dataTable value="#{orderController.orderList}" var="order"
                                     styleClass="table table-striped">
                            <h:column>
                                <f:facet name="header">#</f:facet>
                                <h:outputText value="#{order.orderNo}" escape="false"/>
                            </h:column>
                            <h:column>
                                <f:facet name="header">Cliente</f:facet>
                                <h:outputText value="#{order.client}" escape="false"/>
                            </h:column>
                            <h:column>
                                <f:facet name="header">Data</f:facet>
                                <h:outputText value="#{order.date}" escape="false"/>
                            </h:column>
                            <h:column>
                                <f:facet name="header">Status</f:facet>
                                <h:outputText value="#{order.status}" escape="false"/>
                            </h:column>
                            <h:column>
                                <f:facet name="header"></f:facet>
                                <h:form>
                                    <h:commandButton action="#{orderController.orderDetail}" value="Detalhe" styleClass="btn btn-info"/>
                                </h:form>
                            </h:column>
</h:dataTable>

I’m showing a list of orders and each list has a button “Detail” that will redirect the user to the orderDetail.html page inside views/fornecedores.

I’ve debugged and when I click on the commandButton, it is not calling my bean function.[

I have also tried this: <h:commandButton action="views/fornecedores/orderDetail.html" value="Detalhe" styleClass="btn btn-info"/> and nothing, it keeps redirecting me to the same page, orderSearch.html.

What I need is to call the method that will receive a orderNo parameter and will load the object and redirect to the orderDetail.html page.

What am I doing wrong or what is the best way to this approach?

Answer 1

In this particular case, that can happen when you’re nesting forms which is illegal in HTML. This can also happen when the #{orderController} is request scoped and the orderList content depends on a request based value which causes that the list is incompatibly changed when the form submit is to be processed.

So, make sure that you aren’t nesting multiple <h:form> components in each other and make sure that the #{orderController} is a @ViewScoped bean and that you aren’t manipulating the orderList in its getter method.

As to your concrete functional requirement, the <h:link> with <f:param> and <f:viewParam> is a more sane approach for this. It’s bookmarkable and more SEO friendly. See also Communication in JSF 2.0 – Processing GET request parameters.
