ColdFusion, CFC Binding, Ajax Proxy and Updater 1

This week I got a much belated chance to play with some of the CF8 Ajax features I've never gotten around to. I've had CF8 developer's edition on my home PC for a while, but never worked for a place that actually had CF8 in production so I didn't get to play much with the new stuff. I had a big show stopper though. Both my cfgrid bind attribute and my cfajaxproxy tag weren't working. The CFC's I wanted to bind to were web accessible, but there were in a series of subdirectories. ColdFusion, however, kept constructing Ajax code to look in the web root.For instance, my CFC was here:
[code]http://www.myserver.com/admin/webservices/userFacade.cfc[/code]I would put this code in my page:
[code]<cfgrid bind="cfc:admin.webservices.UserFacade.getUsers()">[/code]And
[code]<cfajaxproxy cfc="admin.webservices.UserFacade" jsclassname="UserFacade">[/code]But in both cases, I would see JavaScript get generated like this:
[code]var _cf_UserFacade=ColdFusion.AjaxProxy.init('/UserFacade.cfc','UserFacade');[/code]
This obviously caused a 404 (Not Found) since the file didn't exist in the root directory.
Thanks to Andrew Scott from the CF-Talk list for mentioning this behavior was a known issue with the original release of CF8 and was fixed in Updater 1. Sure enough, I had neglected to update my home computer with Updater 1. I stopped CF, downloaded the updater, installed it, started CF and I was back in business.
I hope this helps someone. I mainly blogged it because I googled for a long time and never found anything to help me. Thanks again Andrew!

I've been having the EXACT same problem, and sure enough, my production environment is running 8.0.0. Contacting IT now about upgrading. Thank you for the tip... spent HOURS finding a solution...

My cfgrid calling a cfc was working just fine on 8.0.0 until I applied the 8.0.0 security patch. That patch broke the cfgrid call and now I have this problem. Unfortunately I have to have the patch due to PCI reasons, but I found this comment about it being fixed in cf8.0.1 and with the hot fixes and security patches for that. I tried to apply the 8.0.1 update, my websites worked fine, but I got a blank page when going to the coldfusion administrator. Thus, I had to back out the update. A bigger problem is that you don't get much assistance from Adobe on this and the product seems to be lacking since they bought it from macromedia. Shame. I now have to find some type of workaround until I can do the update!!!!
