Been trying to increase the width of the textfield within the FileUploadField component.

Have tried setSize, but it only changes the height.

Tried getFileInput().setSize(..) (after render event) but seems to have no effect.

Any ideas?

Edit:

If I call setAutoWidth(true), the field itself seems to expand, but not the textfield within the component, as seen by the Browse button moving on the right side.
