I want to test Bug 887160. After subscribing to a CalDAV calendar I'm not prompted for username and password as expected. Instead nothing happens. The error console shows:

Error: winUtils is null
Source File: resource://gre/components/nsPrompter.js Line: 380

Error: runnablePrompter:run: [Exception... "'[JavaScript Error: "winUtils is null" {file: "resource://gre/components/nsPrompter.js" line: 380}]' when calling method: [nsIPromptService2::promptAuth]"  nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)"  location: "JS frame :: resource://gre/components/nsLoginManagerPrompter.js :: <TOP_LEVEL> :: line 577"  data: yes]

Mark, could you help to verify if this problem is caused by your changes in Bug 875157? 
At least the reported code location was last touched by this bug.

Yep - sorry about that...
Blocks: 762400
OS: Windows 7 → All
Hardware: x86_64 → All
This patch should fix it and seems reasonable to me and still addresses the use-case in bug 762400.

Drew, this is a patch for the "skip prompts from the hidden window" - if the window doesn't support nsIDOMWindowUtils I think it's safe to assume it's not hidden from the POV of our thumbnail work...

I can confirm that the problem is fixed. The expected dialog is displayed again.

Could you take care to port back the fix to the affected aurora (mozilla24) branch?

Only use winUtils if not null

[Approval Request Comment]
Bug caused by (feature/regressing bug #): 875157
User impact if declined: Lightning (Calendar) product will be broken in Thunderbird
Testing completed (on m-c, etc.): Landed on MC
Risk to taking this patch (and alternatives if risky): Low risk - fixes regression by reverting behaviour back to before bug 875157's patch - and that bug is only required for background thumbnails which aren't yet used directly on the 24 branch

Does anyone happen to know which nsIDOMWindow implementation fails to return an nsIDOMWindowUtils from nsIInterfaceRequestor? I would be curious to know!

If I read the calendar source code correct the Calendar password prompt will be opened using nsIAuthPrompt2::promptAuth() in

Before that it creates the prompt using nsIPromptFactory::getPrompt() but I'm not sure what object is actually passed in as the nsIDOMWindow aParent argument but it seems to be some calendar object.

When triggering the error in comment 0 the arguments passed to openModalWindow() are:
> domWin=[xpconnect wrapped (nsISupports, calICalendarProvider, nsIInterfaceRequestor, calIFreeBusyProvider, nsIChannelEventSink, calIItipTransport, calISchedulingSupport, calICalendar, calIChangeLog, calICalDavCalendar, nsIDOMWindow)] 
> uri=chrome://global/content/commonDialog.xul 
> args=[xpconnect wrapped (nsISupports, nsIWritablePropertyBag2, nsIWritablePropertyBag)]
Stefan, can you please verify this is working for you now in Thunderbird 24 and 25?
