Failed retrieving values

[Çağlar Karahan]

I got an error "Failed retrieving values required to evaluate condition"
when checking service-type in if condition in default config file. It seems
that the client does not send requests with service-type attributes. My
question is, is it necessary to send service-type attribute by client side
or do we need to check also if there is a service-type attribute?

Thanks for your suggestions.
