fileupload trigger

I'm using the fileupload component since 2.2.1 release. Now with 3M3 I recognized that something changed.
I triggered the fileupoload in my managed bean with context.execute("fileupload.upload()").
But it seems that this function is deprecated?!?

Any idea how to trigger fileupload with javascript or with a custom button in 3M3 or 3M4?

Hi,
I've been trying to achieve that for a while... has anyone found a way to do that?
I've tried to simulate a click on all the elements of

Code: Select all

<div class="ui-fileupload ui-widget">

(which seems to be the root element for the upload control) using jQuery, but I've got no success on that. I also looked at the fileupload.js, but (if I'm not wrong) it doesn't seem to have any function for show the upload box (to select the files)...
Any ideas?

Using:
Primefaces 3.3.1; Mojarra 2.1.10; Tomcat 7.0.23; Chrome 18; Ubuntu Linux 12.04
