parseAndCropXhtml aborts and stops all rendering of messages

[ghost]

I've got a member in a chat who uses iChat (I believe, it might be Adium) which causes problems. The following error is received in Firefox's debugging console:

function Candy.Core.Event</self.Jabber.Message() " - error - " Error: Syntax error, unrecognized expression: Bygglovsgruppen har möte, efter mötet med bygglov i går morse. Stackspårning: Sizzle</Sizzle.error@https://chat.kulturhusfestivalen.se/extlib/jquery.js:1464:2 Sizzle</Sizzle.tokenize@https://chat.kulturhusfestivalen.se/extlib/jquery.js:2079:1 Sizzle</Sizzle.select@https://chat.kulturhusfestivalen.se/extlib/jquery.js:2480:11 Sizzle@https://chat.kulturhusfestivalen.se/extlib/jquery.js:879:2 .find@https://chat.kulturhusfestivalen.se/extlib/jquery.js:2696:4 jQuery.fn.init@https://chat.kulturhusfestivalen.se/extlib/jquery.js:2816:5 jQuery@https://chat.kulturhusfestivalen.se/extlib/jquery.js:72:3 Candy.Util</self.parseAndCropXhtml@https://chat.kulturhusfestivalen.se/candy.bundle.js:692:9 Candy.View.Pane</self.Message.show@https://chat.kulturhusfestivalen.se/candy.bundle.js:4855:17 Candy.View.Observer</self.Message@https://chat.kulturhusfestivalen.se/candy.bundle.js:3032:13 jQuery.event.dispatch@https://chat.kulturhusfestivalen.se/extlib/jquery.js:4663:1 jQuery.event.add/elemData.handle@https://chat.kulturhusfestivalen.se/extlib/jquery.js:4321:1 jQuery.event.trigger@https://chat.kulturhusfestivalen.se/extlib/jquery.js:4570:5 .triggerHandler@https://chat.kulturhusfestivalen.se/extlib/jquery.js:5304:4 Candy.Core.Event</self.Jabber.Room.Message@https://chat.kulturhusfestivalen.se/candy.bundle.js:2742:21 Candy.Core.Event</self.Jabber.Message@https://chat.kulturhusfestivalen.se/candy.bundle.js:2334:17 Strophe.Handler.prototype.run@https://chat.kulturhusfestivalen.se/libs/libs.bundle.js:1619:17 Strophe.Connection.prototype._dataRecv/<@https://chat.kulturhusfestivalen.se/libs/libs.bundle.js:2470:1 Strophe.forEachChild@https://chat.kulturhusfestivalen.se/libs/libs.bundle.js:771:21 Strophe.Connection.prototype._dataRecv@https://chat.kulturhusfestivalen.se/libs/libs.bundle.js:2459:13 Strophe.Bosh.prototype._onRequestStateChange@https://chat.kulturhusfestivalen.se/libs/libs.bundle.js:3766:17 "Syntax error, unrecognized expression: Bygglovsgruppen har möte, efter mötet med bygglov i går morse."

I don't have a big selection of strings sent from that client causing the problem, but the following is one:
Bygglovsgruppen har möte, efter mötet med bygglov i går morse.
(as you can see it has unicode characters, though I'm not sure they're related)

The issue, after getting some help from that horrible error message, seems to be in candy.bundle.js for the Candy.View.Pane.Message.show method when it is supplied a (probably incorrect then) xhtmlMessage parameter.

The function is at about line 4850 in my copy of the bundled JS and it is the function called here:
if (xhtmlMessage) { xhtmlMessage = Candy.Util.parseAndCropXhtml(xhtmlMessage, Candy.View.getOptions().crop.message.body); }

which looks like this:
self.parseAndCropXhtml = function(str, len) { alert(str); return $("<div/>").append(self.createHtml($(str).get(0), len)).html(); };

...I'll just publish this issue now and can fill out more info later. Does anyone else have this experience - or figure out what happens that causes the error - or should I debug some more and elaborate?

Hi,

this looks to me like the awesome unicode errors because of the cropping. It does most likely crop in the middle of a unicode character..
There are some libraries as far as I remember which handle unicode correctly. Will need to find them again, but maybe what I wrote here helps you already in figuring out how to fix it ;)

I got similar issue, but it was with latest candy dev code.
My solution was changing the event.js in line 863 from
var xhtmlMessage = $($('<div>').append(xhtmlChild.children('body').first().contents()).html());
to
var xhtmlMessage = $($('<div>').append(xhtmlChild.children('body').first().clone()).html());

Yes, I think I'm seeing this same thing

This message from iChat stopped rendering contents for the chat it was sent to + all chats rendered after it. Ouchie!
