Oo just that? I found that earlier but I tought that it wasn`t that. There are errors in your great book (most typos in source code) but it`s still nice one :) Thanks for replay!

Hi Jack,

I am following ur book XMPP programming using javascript and jquery. Till yesterday(17 July 2010) every thing was working fine. I was able to connect to jabber.org xmpp server.
But from today (18 july 2010) onwards I am getting a error

"Microsoft JScript runtime error: 15, securityError, A security sandbox error occured with the flXHR request".

Please help me out.

I am using "http://bosh.metajack.im:5280/xmpp-httpbind" as bosh connection manager.

Thanks for such a nice book!

I have installed Openfire 3.6.4 to work with Metajack's book.

Sketchcast.js from chapter 9 should be updated in several places.

1) .c('field', {"var": "pubsub#persist_items"})
.c('value').t("1") //instead old .t("true")

2) subid variable should be added to the SketchCast object. When subscriber send iq query to get items from pubsub, there should be subid='value_of_subid' included as items attribute. So here are changes:

// subscription callbacks
subscribed: function (iq) {
SketchCast.subid = $(iq).find('subscription').attr('subid');
$(document).trigger("reception_started");
},

// get missed events
SketchCast.connection.sendIQ(
$iq({to: SketchCast.service, type: "get"})
.c('pubsub', {xmlns: SketchCast.NS_PUBSUB})
.c('items', {node: SketchCast.node,subid:SketchCast.subid}),
SketchCast.on_old_items);

And do not forget subid:null after disconnection and errors.

The GitHub repository of the code is kept up to date with all errors people have reported to me. You can find it at http://github.com/metajack/profxmpp

Do you still get this error? My site was briefly down due to physical server maintenance about a week ago, but has since been fixed.

If you still get this error, what is the URL your application runs at? You cannot use the flXHR plugin from file:// URLs, so that would be my first guess.

Have you noticed that the strophe.flxhr.js location has changed? It's now under script/plugins folder, if you extract files according to the instructions in the book.

Correct line:
<script src='../scripts/plugins/strophe.flxhr.js'></script>

My laptop was recently upgraded to Windows 7 (IIS 7) from Windows XP (IIS6), and Visual Studio was upgraded concurrently form 2008 to 2010. Ever since, whenever I try to run and debug my application I get the following message:

Microsoft JScript runtime error: 15, securityError, A security sandbox error occured with the flXHR request.

I thought it might be something to do with VS 2010, so I re-installed VS 2008. That's having the same problem (but it worked perfectly before the upgrade). At this point I assume the problem has to do with IIS 7. I'm not seeing a whole lot of threads on google related to this, but there are some. None of the solutions have helped however. Does anyone have any ideas on what to check? This is getting pretty frustrating and I'm spinning my wheels way too long now. :-(

This can happen if you try and view the page using the flxhr code from a file:// URL instead of an http:// URL. Be sure the url you visit in your browser is a http:// address and it should work fine.

If that doesn't fix it, check that your crossdomain.xml file is correct and has the right mimetype.

If neither of those work, you might try contacting the author of flxhr at flensed.com.
