Using PF10 (in a JoinFaces project), I'd like the Upload File dialog for choosing a file to show up when the page loads (i.e., without waiting for the user to click on the Choose button of <p:fileUpload/>). How can I do that?

You could use client side API show() function for this. But it seems more and more browsers are blocking triggering a click by script on an input type="file". See https://github.com/primefaces/primefaces/issues/7772
You could take your chances and try to hijack a mouse move event to trigger a click on the upload input, which is answered on this question: In JavaScript can I make a "click" event fire programmatically for a file input element? But I don't really like that hack.
