If i call a Rest-Service this way: /foo?method=test&arg0=xxxx&arg1=yyyy everything works as expected.

But If I change the order of the arguments like this: /foo?method=test&arg1=yyyy&arg0=xxxx yyyy is used as first and xxxx as second argument.

I actually found the problem when using Zend_Rest_Client to access the Rest-Server - and Http_Client sometimes disorders the arguments in the request.

This little patch solves the problem:

                     }
+                    ksort($calling_args);
