I am suddenly having a strange error. Whenever I try to do anything
in my rails application when it’s running on WEBrick it just dies with
an ArgumentError 0 for 1 while in Mongrel it doesn’t die but every
redirect_to generates a static page saying “you are being redirected”
it never actually redirects from this page though.
I’ve tried re-installing mongrel, activerecord and rails but that
doesn’t seem to be helping.
Please post the full backtrace generated by webrick and we may be able
to guide you a little better. Most likely it’s a simple problem. In
your debugging you will probably never have to reinstall any of those
things (not set in stone of course, I’m sure some people have to but
it’s a rarity. I’ve certainly never reinstalled them).

Mongrel serves the pages but chokes on any redirect_to statement.
Mongrel gives the error listed above for any and all requests but
renders the pages and handles data properly.

redirect_to generates a static page saying “you are being
redirected”
it never actually redirects from this page though.I’ve tried re-installing mongrel, activerecord and rails but that
doesn’t seem to be helping.
In addition to Chuck’s advice, I would first try to consider recent
changes.
When did this symptom appear. Can you revert to an earlier version.
Then slowly add back changes.
I’ve got a feeling it might be environment related - new plugin?
environment.rb change? routing change?
good luck. One’s can be painful.

Alright, I’ll admit that I don’t know what it is off the top of my
head. I’m sure it’s user error because google isn’t brimming with
answers to your question, but I’m not sure what kind of user error.
What I would suggest is to go out and get a copy of the ruby-debug
gem, include it in development.rb, and toss debugger in your
environment file somewhere. Step through your program and find out
where this mess is starting. (try set autolist then type n enter
once and then enter again and again until you see problems).
This has helped me time and time again when I just have no clue about
an error, hopefully it’ll help you too.
The other option at hand is to diff with the latest revision if you’re
using subversion and see what all you’ve changed. Also helpful and
sometimes much faster but not everyone is using version control. Also
not very helpful if you commit big changesets.
Hope that helps, you’ve got an interesting problem for sure.
Chuck V.
Thanks, I’ll give that a try.
It would seem that whatever I’ve done has broken entirely different
applications that worked that last time they were touched too.
Okay the last thing it tries to do before throwing the error is
reset_after_dispatch
I don’t have any plugins currently installed for this application. I
have acts_as_attachment installed in another application however that
shouldn’t bleed over shout it?
I haven’t changed much of the default setup for this one yet (it’s
pretty simple). I did uncomment the # map.connect ‘:controller/
service.wsdl’, :action => ‘wsdl’ line in routes. I tried commenting
it out again but that didn’t help any.
Like Chuck says it must be my app but I have no idea what I could have
done to cause this. I just tried running it on a clean install of
everything on a different machine and it is behaving the same way
which should permanently put to rest the slightest doubt that it is my
code that is doing it.

Okay after stepping back, for lunch and other work, I have a good idea
of the general cause. I just have to figure out what part of the
suspect code is causing the problem.
Thanks for your help guys.

It would appear that the source of the problem was somewhere in the
code for recipes 15.8 and 15.9 in the Ruby Cookbook. I wasn’t able to
figure out what was causing the problem so I ripped the whole thing
out and used a different resource.
That’s what I get for being lazy and copying verbatim from a book.

It looks like I’m getting the same error. After upgrading to rails
1.2.3, I get the same dispatch error:
Wed Aug 01 22:44:37 -0700 2007: Error calling Dispatcher.dispatch
#<NameError: cannot remove Object::VERBOTEN_TAGS>
On Jul 31, 9:00 am, “[email protected]” [email protected]
I began experiencing this same problem when I updated my app to Rails
1.2.3 and mongrel 1.0.1 on 2 Aug, a google search brought me straight
to this post.
