I encountered this bug on Safari 1.3.2 and Opera 9.02 using Prototype
1.5.0 rc1. The problem is that when using an Ajax.Request object with
asynchronous=false, the onComplete function is called twice.
The respondToReadyState (prototype.js line 797) function was being
called multiple times for the finished request. I added the following
code at line 798 and it fixed it.
if (this.transport.onreadystatechange == Prototype.emptyFunction)
return;
If someone who is more familiar with XMLHttpRequests would like to look
into this and apply a patch (either the one mentioned above, or a
better one that stops the respondToReadyState from being called the
extra time) to the prototype code, that would be great.
