ActionWebService SOAP Call Fails w/ Parameters - TypeError (can't modify frozen object):

Reported by:	Joe	Assigned to:	anonymous
Priority:	high	Milestone:
Component:	ActionWebService	Version:	1.0.0

Description

When moving to ruby version 1.8.3 this error happens when invoking a SOAP web service using parameters.

Stack Trace: TypeError (can't modify frozen object):

I've tried this with both the latest rails and edge rails.

If I move back to ruby 1.8.2 this error no longer appears - however I need some other features from ruby 1.8.3 so I'm a little stuck here.

Is there a workaround for this yet?

Thanks.

This is a big hack, mostly because I have absolutely no idea what else this affects. I stumbled through fixing this with a lot of breakpoints and guessing. It made my problems go away, though. Both changes must be made together or you just get different error messages.

Hi guys,

Think I've found the problem, I've reproduced it with SOAP4R 1.5.5 on Ruby 1.8.2.

Could you try this patch (a quick workaround) against lib/action_web_service/protocol/soap_protocol.rb?

           request.set_param(params)
           envelope = create_soap_envelope(request)
           SOAP::Processor.marshal(envelope)

Let me know if this fixes it for you, and I'll try come up with a better solution.
