ExtJS Cannot read property 'stopEvent' of undefined

Im using ExtJS 3.3 and i have a combobox, what im trying to do is prevent the click action on certain items in the combobox.

The code im using is as follows;

listeners: {
    beforeselect: function(combo, record, index, e) {
        if(record.json[3] === false) {
            e.stopEvent();
        }
    }
},

It actually works, preventing a user from clicking an item, but the problem is that it also causing an error, as follows;

Cannot read property 'stopEvent' of undefined

If anyone has managed to get this going without causing an error message, that would be awesome if you could share it.

Cheers,

Have you checked the docs? They state the beforeselect event doesn't have four parameters.

To prevent the selection, as per the same docs:

Return false to cancel the selection.

So to summarize:

listeners: {
    beforeselect: function(combo, record, index) {
        if(record.json[3] === false) {
            return false;
        }
    }
},
