Google Apps Script Close()

Question

Is it possible to close a UI window that has opened in Apps Script?

I think the answer is no per: http://code.google.com/p/google-apps-script-issues/issues/detail?id=474&can=1&q=.close%28%29&colspec=Stars%20Opened%20ID%20Type%20Status%20Summary%20Component%20Owner

but I wanted to see if there were other opinions.

I have a "Waiting window" that pops up, that I want to close when the activity is finished.

---

var app = UiApp.getActiveApplication();

var ss = SpreadsheetApp.getActiveSpreadsheet();

var sheet = getSheetWithSubmissions(ss);

// create UI app, this works fine

app = createWaitPleaseUI(sheet);

ss.show(app);

//simulated activity

Utilities.sleep(5000);

//this doesn't work despite being in the documentation

app.close();

---

Think this is not possible but wish Google would dump it from their documentation if it can't be done.

As a workaround, I can bring up a second GUI saying "work complete, click OK" and then it works fine.

You have to return the app object for any changes to be updated to it, even closing.

Change your last line to return app.close() instead.
