How to hide/show a tab on a dialog base on an event of item? Resolution: In the sample code, we add a listener to listen ‘change’ event for checkbox. <listeners jcr:primaryType="nt:unstructured" selectionchanged="function(comp, val, isChecked) { var dialog = comp.findParentByType('dialog'); var tabpanel = dialog.findByType('tabpanel’); if (isChecked) { tabpanel.hideTabStripItem(1);//Hide tab at 2nd position } else { tabpanel.unhideTabStripItem(1) } } " />
