Problems with methods in v. 2.1.6

[Tommy Abrahamsson]

Hi

After upgrading to 2.1.6 all my methods seemed to stop working. It complains 
about Number of return
arguments does not match template.
My first guess is, that it doesn't create the proper file in 
/var/cfengine/rpc_in/ so it can't
determine the prototype. When I run cfagent, it's looking for 
127.0.0.1_192.168.1.2
_SimpleMethod_MD5=xxx, but the physical file is called 
localhost_localhost_SimpleMethod_MD5=xxx.

I would very much like the methods to start working again, as it's a really 
cool feature of
cfengine.
Thanks in advance for your help.

Anyways, my policy:

methods:
      myclass::
      SimpleMethod(null) action=cf.simple returnvars=null returnclasses=null 
server=localhost

and the /var/cfengine/modules/cf.simple, looks like this (taken from the web):

# cf.simple
control:
         MethodName       = ( SimpleMethod )
         MethodParameters = ( null )
         actionsequence   = ( timezone )
     ####################################################
     alerts:
     myclass::
       "This simple method does nothing"
       ReturnVariables(void)
       ReturnClasses(void)


The output when I run cfagent:

...
