[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-3459) IE6 (very specific version) Crash on Seam Remoting Callback

[Andy Siu (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBSEAM-3459?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12433207#action_12433207 ] 

Andy Siu commented on JBSEAM-3459:
----------------------------------

I found a problem after this fix.
Under some condition, setTimeout is run after asyncReq.send(envelope);
which makes onreadystatechange loss

I am using
Microsoft Windows XP - Professional, SP3
IE 7.0.5730.13

I try to fix it and found the following modification works

window.setTimeout(function() {
  asyncReq.onreadystatechange = function() {
  if (rcb) rcb(asyncReq, callback);     
  };
  asyncReq.send(envelope);
}, 0);

> I tracked the issue down to one line of javascript code in remote.js
>    req.onreadystatechange = function() {};
> The following thread discusses the problem is with an old version of the JScript.dll 5.6.0.8820 which is the same version I've got on a laptop here.

> One solution is to upgrade JScript.dll to  5.6.0.8831 
>    http://www.microsoft.com/technet/security/bulletin/ms06-023.mspx 
> Or we can do what they did in GWT which is to move the req.onreadystatechange out of the scope of the current function

>     	req.onreadystatechange = function() {};
