Unselect combobox throw error

[arma]

Hi,

When i unselect a combo, it throws error "TypeError: Cannot read property 'length' of undefined".
For example i have a combo with value 1 selected and then i run in console $('#mycombo').combobox('unselect',1);

Is it a bug or i call the method in a wrong way?

Note: i have attached onChange event in the combobox.

Thanks

Ah oke i got it,

when method unselect called, it will trigger onchange which will return newVal parameter as undefined. Solved now.

Code:

onChange: function(newVal, oldVal) {
                if(newVal === undefined){
                    return false;
                }
