Opening a dialog fails on Windows 10

See original GitHub issue

Hey great library!. I’ve been using it for a personal project for a few months and as i try to port my app to windows 10 i noticed this.

Offending code is called after parsing the json recieved from window.external.invoke

let file_name = view.dialog(Dialog::SaveFile, "Choose Database File", "");

And in another spot

let file_name = view.dialog(Dialog::OpenFile, "Choose Database File", "");

Both react the same way, i never see the file dialog and it immediately returns an empty string. Any ideas what might cause this?

Of coarse here is a test program showing the bug

extern crate web_view;


use web_view::WebView;
use web_view::MyUnique;
use web_view::Content;
use web_view::Dialog;
use web_view::Alert;
use web_view::run;

const HTML: &str = r#"
<DOCTYPE html>
<html>
  <body>
      <button onclick="window.external.invoke('open')">Open File Dialog</button>
      <button onclick="window.external.invoke('save')">Save File Dialog</button>
      <button onclick="window.external.invoke('directory')">Choose Directory Dialog</button>
      <button onclick="window.external.invoke('alert-info')">Info Alert</button>
      <button onclick="window.external.invoke('alert-warning')">Warning Alert</button>
      <button onclick="window.external.invoke('alert-error')">Error Alert</button>
  </body>
</html>
"#;

fn callback(view: &mut WebView<()>, arg: &str, user_data: &mut ()) {
    match arg {
        "open" => {
            println!("Attempting to open 'OpenFile' dialog");
            view.dialog(Dialog::OpenFile, "Test Open Dialog", "");
        },
        "save" => {
            println!("Attempting to open 'SaveFile' dialog");
            view.dialog(Dialog::SaveFile, "Test Open Dialog", "");
        },
        "directory" => {
            println!("Attempting to open 'ChooseDirectory' dialog");
            view.dialog(Dialog::ChooseDirectory, "Choose Directory Dialog", "");
        },
        "alert-info" => {
            println!("Attempting to open info alert");
            view.dialog(Dialog::Alert(Alert::Info), "Info Alert", "");
        },
        "alert-warning" => {
            println!("Attempting to open warning alert");
            view.dialog(Dialog::Alert(Alert::Warning), "Info Alert", "");
        },
        "alert-error" => {
            println!("Attempting to open error alert");
            view.dialog(Dialog::Alert(Alert::Error), "Info Alert", "");
        }
        _ => {}
    }
}

fn main() {
    let (_, _) = run("open dialog test",
            Content::Html(HTML),
            Some((500, 500)),
            true,
            true,
            |_|{},
            callback,
            ()
        );

}

All of the alerts work so ignore those, but none of the file dialog’s ever open

~This also happens to me on Window 10, but only on the stable-msvc toolchain. Dialog functions normally when built on the stable-gnu toolchain.~ nvm, still having the same problem.
