Hey,
the model selection is a data array which can not be accessed by []. But still,
it has a length property natively attached which brings some browsers like
opera to act like it would be a real array. But the browsers do have the same
problem which results in a empty array as representation. Use getItem and
setItem as method if you use data arrays and you will be fine. For more
details, check the API of the data array.
Regards,
Martin
