Combobox selected but not returned any value

[arma]

I've faced this problem and can not find why. Here's my code on document ready.

Code:

$('#cb-year').combobox({
            valueField: 'id',
            textField: 'text'
});

$('#cb-year').combobox('loadData', years); //years is json variable 
$('#cb-year').combobox('setValue', '2015')
;

When i click combobox, i see '2015' is higligted, but when i run $('#cb-year').combobox('getValue') in browser console, it returns empty string.
if i ('getData'), the data returned seems correct [{id:'2015', text: '2015'}, and so on].

Any clue why ?

Hi Jarry,

I use 1.3.6. Do you have hosted minified jeasyui with that version, so i can change the external dependency/resource in you fiddle ?

Thanks.
