    <p>Active Index is not getting updated automatically. ReaD in a few posts that by placing the tabView on a form it works. Or by including <code>&lt;p:ajax event="tabChange"/&gt;</code> in the tabview it works. But nothing seems to work</p> <p><strong>xhtml</strong></p> <p><strong>Sample 1 : automatic updates</strong></p> <p> </p> <pre><code> &lt;p:tabView id="categoryTabView" var="promoArticle" value="#{promotionDetailBean.artDTOs}" activeIndex="#{promotionDetailBean.activeTabIndex}"&gt; &lt;p:tab id="categoriesTab" title="#{promoArticle.categoryName}"&gt; &lt;p:dataTable id="promotionDetail_dataTable" var="articlePromo" value="#{promoArticle.artVO}" selection="#{promotionDetailBean.selectedArt}" rowIndexVar="rowIndex"&gt; &lt;p:column id="select" selectionMode="multiple" /&gt; &lt;p:column id="barCode"&gt; &lt;h:inputText id="barCodeInputTxt" value="#{articlePromo.barCode}" styleClass="inputTextStyle" onchange="onSuggestedValueChange('categoryTabView',#{promotionDetailBean.activeTabIndex}, 'promotionDetail_dataTable',#{rowIndex},'originalCostInputTxt')" /&gt; &lt;/p:column&gt; &lt;/p:dataTable&gt; &lt;/p:tab&gt; &lt;/p:tabView&gt; </code></pre> <p><strong>Sample 2: Updating on tabChange event</strong></p> <pre><code> &lt;h:form id="form"&gt; &lt;p:growl id="growlm" showDetail="true" /&gt; &lt;p:tabView id="categoryTabView" var="promoArticle" value="#{promotionDetailBean.artDTOs}" &gt; &lt;p:ajax event="tabChange" listener="#{promotionDetailBean.tabChanged}" update=":growlm" /&gt; &lt;p:tab id="categoriesTab" title="#{promoArticle.categoryName}"&gt; &lt;p:dataTable id="promotionDetail_dataTable" var="articlePromo" value="#{promoArticle.artVO}" selection="#{promotionDetailBean.selectedArt}" rowIndexVar="rowIndex"&gt; &lt;p:column id="select" selectionMode="multiple" /&gt; &lt;p:column id="barCode"&gt; &lt;h:inputText id="barCodeInputTxt" value="#{articlePromo.barCode}" styleClass="inputTextStyle" onchange="onSuggestedValueChange('categoryTabView',#{promotionDetailBean.activeTabIndex}, 'promotionDetail_dataTable',#{rowIndex},'originalCostInputTxt')" /&gt; &lt;/p:column&gt; &lt;/p:dataTable&gt; &lt;/p:tab&gt; &lt;/p:tabView&gt; </code></pre> <p>I need to identify the cell on "onChange " event. But the activeIndex is always 0, the initialized value. The event doesn't get call.</p> <p><strong>bean</strong></p> <pre><code>private Integer activeTabIndex = 0; public Integer getActiveTabIndex() { return activeTabIndex; } public void setActiveTabIndex(Integer activeTabIndex) { this.activeTabIndex = activeTabIndex; } </code></pre> <p><strong>bean</strong></p> <pre><code>public void tabChanged(TabChangeEvent event){ TabView tv = (TabView) event.getComponent(); this.activeTabIndex = tv.getActiveIndex(); } </code></pre> <p>But the event is not getting trigerred. Nor getting updated automatically.</p> <p>What could be the probable issues ?</p> <p>Thanks, Shikha</p>

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).
