Current Result
zul.sel.wpd:3684 Uncaught (in promise) TypeError: option.isSelected is not a function
at init._changeSelect (zul.sel.wpd:3684)

Expected Result
"Item 3" is selected
Debug Information
there are listgroups (zul.sel.Optgroup) in the listbox which don't have an isSelected method
Workaround
override the _changeSelect method to only handle zul.sel.Option widgets
zk.afterLoad('zul.sel', function() { var xSelect = {}; zk.override(zul.sel.Select.prototype, xSelect, { _changeSelect : function(option, toSel) { if(option.$instanceof(zul.sel.Option)) { return xSelect._changeSelect.apply(this, arguments); } return false; } });//zk.override });//zk.afterLoad
