We’ve got a site running on Rails 2.2.2 with Prototype 1.6.0.3 that uses  
the rails/auto\_complete plugin from github. We just discovered that,  
in IE7 (haven’t tried IE8 yet), when a user types a name into the  
auto\_complete text field, the query gets sent to the server fine and the  
server returns it’s results fine, but then IE doesn’t do anything with  
it. As far as the user can tell, absolutely nothing happened. If, after  
that first request, the user then changes the text in the text field, a  
new query is initiated, and from then on (until the page is reloaded)  
auto\_completing works just fine.

On a whim, downgraded Prototype to 1.6.0.1, and suddenly IE started  
behaving properly.

I find it hard to believe that we’re the only one’s experiencing this.  
Has anyone else seen this? Or are there really that few developers that  
are using auto\_complete in conjunction with Prototype 1.6.0.3 that have  
also bothered to check to see if it works in IE?

I guess it depends on how you have it coded. Some of the autocomplete  
stuff was moved out into a plugin which may not be maintained anymore.

Yeah, I’m using that plugin. But the point is that whether or not it  
works doesn’t depend on the plugin, it depends on the version of  
Prototype. It doesn’t work with Prototype 1.6.0.3 or 1.6.0.2, but I  
can’t believe this has been an issue since January 2008 (when 1.6.0.2  
was released) and nobody’s noticed until now.
