20050520 trunk Switching between mail folders doesn't work most of the time. The selected folder highlights, but the message headers from the previous folder remain in the header pane. Clicking back and forth will eventually get the proper headers to display in the header pane.

Make that 20050521.

regression from Bug #281988

Notes for any xpconnect guys that might be reading: Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" The line of code is GetMessagePaneFrame().location = "about:blank"; The previous line of code is if (GetMessagePaneFrame().location != "about:blank") GetMessagePaneFrame() returns window.content for historical reasons.

We should retest once bug 295122 is fixed.

So... how do I get to where I can reproduce this? The tbird UI comes up completely busted over here, the only menu option is "Folders", there is an XML wellformedness error somewhere (there's a big gray bar with a single red caret in it). I get this in every single one of my tbird builds.

On a just downloaded Windows hourly build: Error: uncaught exception: [Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: chrome://messenger/content/msgMail3PaneWindow.js :: ClearMessagePane :: line 1227" data: no] I don't see a pattern as to how it happens but if I click around from inbox to other inboxes or folders, eventually it seems to happen.

marcia has seen this on Mac OS X as well.

OK. So is this reproducible with a newsgroup account? I subscribed to a few mozilla.org newsgroups and have been clicking about and there have been no issues... Make sure to test builds pulled after "2005-05-23 11:00 PDT", in any case. Is this still a problem in such a build?

this was fixed by Bug #295122

whoops I clsoed this prematurely. It worked the first time I switched but then I got the same JS error again.

upgrading the status on this as the builds aren't really useable if you can't read mail in different folders.

Scott, how do I go about reproducing this? Do you see it with a newsgroup account?

just switch folders. yes I see it with news, imap and pop accounts. ditty for local folders. Just start up thunderbird, click on a message and then try to switch to another folder. Note the inability to do so :) You need to have displayed a message for us to try to clear the message pane which triggers the failure.

ditto for me as well --can also reproduce with RSS account (feeds). tested with 2005052305-trunk tbird bits on linux fc3.

> You need to have displayed a message First time anyone mentioned that in this bug... (or in bug 281988). Yes, with that addition to the steps to reproduce I can see this. Looking into it.

So what's happening here is that XPCNativeWrapper enforces read-only-ness of IDL attributes and window.location and document.location are both read-only. The setter is implemented via the nsWindowSH::SetProperty and nsDocumentSH::SetProperty hooks. For perfect compat we could try to make XPCNativeWrapper deal with these two special cases (are there others?), I guess. For a just-Thunderbird-for-now fix, setting window.location.href instead of window.location should work. jst, thoughts on hacking knowledge of location on window/document into XPCNativeWrapper?

I think I'd rather see us change code that uses XPCNativeWrapper (directly or not) be explicit and setting location.href when that's what they really want.

That patch should fix bug 295266 too, if I understand the steps to reproduce correctly.

Is it just me or the bug is still here with News & Blogs folders? 1 highlight a feed folder 2 highlight an item of this feed 3 highlight an other folder (tested on 2005052401 and 2005052411)

Oliver, how do I get to the point where I have the "News & Blogs" folders to test with? I tested this with newsgroup folders, and those do work...

RSS folders are working fine here. I'm not seeing the JS exception at all when switching RSS folders.

I am seeing the problem described in comment 26 in a thunderbird I just finished building from fresh source. This is what I see in the JavaScript console: Error: invalid 'in' operand window Source File: chrome://messenger/content/mailCore.js Line: 152

I haven't had the time to make sure when exactly it started, what I can say is: - the 5/20 zip build is ok - i can still reproduce with 5/24 17, newly generated %appdata%\Thunderbird folder, only one account and 2 feeds added - i see the above mentioned 'in' js error too (which i didn't see with 5/20) - no problem switching to the thrash folder, only between two feeds Steps: 1. Tools>Account Settings>Add Account>RSS News and Blog>... 2. Manage Subscriptions > Add a feed, eg http://www.extensionsmirror.nl/peter6/firefoxfeed.xml and make sure it's fine (might need restart) 3. Same as 2, eg http://www.mozilla.ru/unghost/thunderbird/thunderbirdfeed.xml 4. click a folder, then an item, then the other folder --> Error: invalid 'in' operand window Source File: chrome://messenger/content/mailCore.js Line: 152 --> Hourglass mouse cursor --> No switch

When subscribing to the feed did you disable article summaries?

Paste feed url and click ok. Default account settings.

Email folders still not working properly with 5/23/2005 build. Please reopen.

using 2005052505-trunk tbird bits, I can still reproduce this going btwn an RSS account (full page display, the default) and any other account (IMAP, POP, Local Folders or news) --basically the same results Oliver sees in comment 30. should this be reopened, or a new bug filed?

> Email folders still not working properly with 5/23/2005 build. That would predate this patch being checked in. Please do test with builds that might conceivably have the bug fixed. ;) I'm looking into the RSS issues.

Seems to be working, but the "snap" or response seems to lag.

Any new bug will only get duplicated against bug 295520.

Ah, yes. Good catch, Neil. That's using window.frames[i], indeed. That's bug 295520 (and the patch there fixes the issue).

(In reply to comment #35) > I'm looking into the RSS issues. looks like the fix for bug 295520 did the trick for this remaining issue! verifying fixed with 2005053113-trunk (tbird).

Bug 300749 if very similar to this.
