‘undefined’ is null or not an object
My ExtJS combobox that was working with Firefox was showing this error message on IE8. The reason for this was a trailing comma in my Javascript matrix.
My matrix was like this:
var shopList= [
[’702038′, ’some dude name’],
[’1120685′, ‘another dude’],
];
After removing the trailing comma it worked in IE too:
var shopList= [
[’702038′, ’some dude name’],
[’1120685′, ‘another dude’]
];
