I'm relatively new to Ext and am upgrading some code to use Ext.JS 4.
The 'add' method seems to have been removed and now I can't assign the grid to the tab named EmployeesTab.
Originally (version 3) we had:
...where employeeGrid is an Ext.grid.PanelCode:listViewTabPanel.getItem('EmployeesTab').add(employeeGrid);
What is the equivalent call in Ext.JS 4?
