295553 - JavaScript call from Flash Movie (over liveconnect) causes XMLHttpRequest to fail on open

Status: RESOLVED INCOMPLETE

(Core :: DOM: Core & HTML, defect)

Description

[tim]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

I have an eLearning application that has a frameset containing 2 frames. In 
one frame, I have some JavaScript that uses XMLHttpRequest object to 
communicate with my server. In another frame, I have a Flash movie that uses 
the swLiveConnect (ActionScript to JavaScript bridge) to interact with 
JavaScript. Whenever the Flash is loaded and calls a function that uses the 
XMLHttpRequest using FSCOMMAND, the following error occurs: 

Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) 
[nsIXMLHttpRequest.open]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" 
location: "JS frame :: 
http://localhost:8080/kworks/javascript/escorte4js.js :: 
eSCORTE4JS_sendRequest :: line 1250" data: no 

Note that this does not occur with IE and the JavaScript that uses 
XMLHttpRequest works fine in FireFox if just plain HTML/JavaScript is loaded 
in the other frame. It's only when Flash Player is involved that I experience 
the crash when calling open() on the XMLHttpRequest object. Happens with 
Netscape 7.2 as well. Any ideas?

Note: My Flash Player version is 7.0.19

Reproducible: Always

Steps to Reproduce:
1. Login to http://209.101.99.68/lacmta/home.jsp (username: admin, password: 
OP32401708) that's an Oh, not a zero
2. Add the eSCORTE4AS2 Demo ... course (Add Course > Register)
3. Launch it in FireFox ... on the menu, choose the last item 
titled "eSCORTE4AS2 for SCORM 2004 Demo SCO"
4. Watch it blow up ...

Actual Results:  
Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) 
[nsIXMLHttpRequest.open]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" 
location: "JS frame :: 
http://localhost:8080/kworks/javascript/escorte4js.js :: 
eSCORTE4JS_sendRequest :: line 1250" data: no 

Expected Results:  
Opened a connection to the server and received XML. Again, if Flash is not 
involved, just HTML and JavaScript, then XMLHttpRequest works great ... so 
it's not my code ;-)

tim, any chance of a URL that shows the bug?  That should make debugging this
much more feasible...

Very possible, yes....  Resolving incomplete until we have more information.
