[FIXED-413] 0.96 SegmentedButton toggle event is fired with null param
STR: create a SegmentedButton with allowMultiple false. When tapping on a button, the previously pressed button receives no reference to the button, instead it's null.
Fix: change line number 17274 from
me.fireEvent('toggle', me.pressedBtn, false);
me.fireEvent('toggle', me.pressedButton, false);
