Xajax Whitespace error?

[eluser]jz[/eluser]
Hello All,

I'm a first-time CI user, and have been using Xajax for more than a year. Just wanted to add this CI-specific "fix" to a dreaded Xajax foible..

After hours of suffering from Xajax's 0.5 Beta 4's cryptic message:

ERROR: ResponseReceived: Invalid response XML: The response contains an unexpected tag or text: {data}.

... I finally figured out that my CodeIgniter MODEL FILE was the culprit. It is loaded and used in one of my Xajax-registered methods in my controller. By using the word "culprit" I'm not suggesting this is CI's fault, btw. It's astonishingly lame that Xajax is vulnerable to this kind of idiotic bug...

Moral of my story:
"When using CodeIgniter+Xajax, check your model files for trailing spaces or lines that are used to generate ajax responses."

Hope this helps someone else,

-moo
