Cross browser event simulation bug (on Firefox).

I had a problem using event simulation on Firefox, although it works fine on Chrome and Safari.

The scenario is that: There is a 'Select File' button, and a hidden input[type='file'] control. Once the button is clicked, the 'click' event is simulated on input[type='file'] control, the open file dialog appear.

On Firefox, the open file dialog does not appear.

Please see the example on jsFiddle:

Hey Khoa,

I'm not sure if it's a bug. You should be careful when simulating actions that normally would be done by userinteraction. I think firefox doesn't allow you to do that.

But I'm not sure.
More about this: http://yuilibrary.com/yui/docs/event/simulate.html#faking

I suggest you make a function (or a widget that shows up) that uses 'Uploader'. Nice is to descent Y.panel and create your own uploader. Both the form as well as your simulation could show this widget, select a file and insert the response int your inputnode. (for progressive enhancement, you could use the upload-button in the original way, and have javascript add a e.preventdefault to it)

Kind Regards,
Marco.
