Hi Tim,

Just out of curiosity I rigged up some code do try the get that behaviour: 
I couldn't get it to work, either. I used lib-gwt-file, not vanilla GWT.

I think Thomas is right, only a handler processing a user-initiated event 
can do the programmatic equivalent of opening the file chooser dialog.

Perhaps a way around this in your case would be to use a hand-crafted 
dialog window, not a native browser alert, and have an option button on 
there open the dialog again for you. UX aspects of this procession of 
dialogs aside ;)

Cheers,
 Dann
