Remoting.js error on Firefox 2

[sherman04]

I've got an onunload handler at a page which issuing an ajax call to SFSB to clean up something and no callback. It runs well on IE but raises error on Firefox saying "Seam is not defined". Actually all works are done properly. The only thing might be that asyncReq.onreadystatechange = function() Seam.Remoting.requestCallback(asyncR...) at Remoting.js gets executed after SFSB returning but at this stage the page is already unloaded and the script doesn't existing at all. Any idea to fix this.

Here is a relevant link talking about it: http://www.ghastlyfop.com/blog/2007/01/onreadystate-changes-in-firefox.html

This should be fixed in CVS now, it would be great if you could test it for me.

Hi Shane,

It seems not fixed yet. I compared the code and saw that you add "if (Seam)" for onreadystatechange handler. I applied that change and tested it again. The error remain the same. I used firebug to debug into it and set a breakpoint at the code. When executing reach the line, Seam object is still there. See below screenshot:

After stepover twice, the Seam object is gone. See below screenshot:

I'm working on 1.2.1 GA released at 2007-03-27 and only applied the change between 1.8 and 1.7 for remote.js.

So at which breakpoint do you get the error? The first or second?

[sherman04]

There is only one breakpoint. I clicked stepover twice, it is still highlighted at the same line.

Can you please raise this in JIRA with a test case (you can base it on the helloworld example if that's easiest).
