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)               }          }   " />
