Hi,

I have a rails-2 app that is using ActionWebService to talk to another  
application.

I’m running my production app from apache, on Linux, using fcgi.

It works fine in my development environment from webrick, and it also  
works using a standard cgi handler, but I’m having trouble when I  
switch to fcgi.

When using fcgi, normal web pages on my app work, and two of my three  
soap methods work. The other works ONCE, and then fails on subsequent  
calls (from somewhere inside actionwebservice) – before it actually  
calls into my controller.

If I kill the fcgi process and re-attempt the request, it works the  
next time, but fails again on all subsequent attempts.

I’ve tried mucking about with adding some diagnostic code to  
action\_web\_service/dispatcher/action\_controller\_dispatcher.rb and what  
I’ve found is that ActiveRecord will always blow up complaining about  
a missing method in nil:NilClass, if I do anythng (such as .inspect)  
with the ws\_request object returned from discover\_web\_service\_request  
on line 49 of that file.

Here’s a backtrace…

undefined method `has_key?' for nil:NilClass <cause xsi:type="n3:NoMethodError" xmlns:n3="http://www.ruby-lang.org/xmlns/ruby/type/1.6"> <message xsi:type="xsd:string">undefined method`has\_key?’ for nil:NilClass
