    <p>I've searched everywhere but couldn't find an answer for my problem, All most all questions and answers are relates to selectOneMenu. Iam using selectOneListbox component in my page as shows below</p> <pre><code>&lt;h:selectOneListbox id="basic" value="#{location.selectedCategory}" style="width: 400px; border: none;" &gt; &lt;f:selectItems value="#{location.categories}" var="y" itemLabel="#{y.title} (#{y.itemCount})" itemValue="#{y}" /&gt; &lt;f:ajax listener="#{location.onNodeSelect}"/&gt; &lt;f:ajax render="itemsPanel" execute="@this"/&gt; &lt;/h:selectOneListbox&gt; </code></pre> <p>My bean,</p> <pre><code> @ManagedBean(name = "location") @SessionScoped public class LocationServiceBean extends BaseService implements Serializable{ public void onNodeSelect(AjaxBehaviorEvent event) { log.info("Entering method : onNodeSelect : "); if(null != selectedCategory){ GetCategoriesAndItemsResponse response =getLocationSupport().getItemsByCategoryAndLocation(selectedCategory.getId(), selectedLocationId); if(response.getStatusCode().equals("0")) { items = response.getData().getItems(); log.info("Items size: " + items.size()); } } } } </code></pre> <p>Problem here is, above listener in the selectOneListBox doesn't get fired when i select items in the list box. Tried with primeface (3.5) component as well, but no luck. </p> <p>UPDATE: added more code</p> <pre><code>&lt;h:form id="venuForm" prependId="false"&gt; &lt;legend&gt;2. Choose Venue&lt;/legend&gt; &lt;div class="control-group"&gt; &lt;label class="span3" for="Country"&gt;Venue&lt;/label&gt; &lt;div class="controls"&gt; &lt;h:selectOneMenu value="#{location.selectedLocationId}" id="select01" required="true" requiredMessage="Location is a mandatory field" styleClass="span8"&gt; &lt;f:selectItem itemValue="#{null}" itemLabel="Select Location" noSelectionOption="true" /&gt; &lt;f:selectItems value="#{location.allLocations}" var="c" itemLabel="#{c.title}" itemValue="#{c.locationId}" /&gt; &lt;f:ajax listener="#{location.loadCategoriesListner}" render=":itemForm:categoriesPanel" execute="@this" /&gt; &lt;f:ajax execute="@this" render=":itemForm:itemsPanel" /&gt; &lt;/h:selectOneMenu&gt; &lt;/div&gt; &lt;/div&gt; &lt;/h:form&gt; &lt;h:form id="itemForm" prependId="false"&gt; &lt;legend&gt;3.

    2. COIf that doesn't work see if selectedCategory is updated with new value after selecting, if it isn't showing new value you have to make a converter for your Category class and specify it in you component(google converters, jsf).

    3. COHI NikolaB, I changed `<f:selectItems value="#{location.categories}" var="y" itemLabel="#{y.title} (#{y.itemCount})" itemValue="#{y}" />` itemValue to get the id of the y object, like this `itemValue="#{y.Id}"`. Guess what, it worked. Also i used `<f:ajax listener="#{location.onNodeSelect}" event="change" render="itemsPanel" execute="@form"/>` as well. Its working now as it should be. Thank you very much for you continues help. Really appreciate it

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
