copied!<p>If you want to show dialog when a specific tab is changed, you can inform a js function about, the tab selected control that it is 2 or not by adding a callback parameter via ajax response:</p> <pre><code>public void tabChangeListener(TabChangeEvent event) { if ( event.getTab().getId().equalsIgnoreCase("tab2") ) { RequestContext.getCurrentInstance().addCallbackParam("index", 2); } } </code></pre> <p>And use:</p> <pre><code> <p:ajax event="tabChange" listener="#{bean.tabChangeListener}" oncomplete="showOrNot(xhr,status,args)"></p:ajax> </code></pre> <p>This will call the js function and it's going to control that the changed tab is 2 or not:</p> <pre><code>function showOrNot(xhr,status,args) { if(args.index==2) { statusDialog.show(); } } </code></pre> <p>Or different approach is defining a value and using <code>visible</code> property of the <code>p:dialog</code>:</p> <pre><code>public void tabChangeListener(TabChangeEvent event) { if ( event.getTab().getId().equalsIgnoreCase("tab2") ) { this.condition=true; } } </code></pre> <p>And <code><p:dialog visible="#{bean.condition}"/></code>. And maybe you need to focus on your first approach and you can give an ID to <code>p:dialog</code> and update it via <code>p:remoteCommand</code>:</p> <pre><code><p:remoteCommand actionListener="#{bean.refreshData}" update="someTab2ElementID dialog" name="refresh" global="true" onstart="statusDialog.show()" oncomplete="statusDialog.hide()"/> </code></pre> <p>Don't forget to give the exact client ID of the dialog in the update property of <code>p:remoteCommand</code>.</p>
