Hi,  
I’m having problem with running “rake appdoc” to generate the  
documentation for rails application.  
I’m receiving next error message:

(in d:/work/RailsTest/testapp)  
rm -r doc/app  
rdoc -o doc/app --line-numbers --inline-source --title ‘Rails  
Application Documentation’ -T ‘html’ doc/README\_FOR\_APP  
app/controllers/application.rb app/helpers/application\_helper.rb  
rake aborted!  
undefined method `exitstatus’ for nil:NilClass

Configuration:  
WinXP SP2  
ruby182-15  
Rails1.0

Could anybody point me at any ideas on how could I overcome this  
problem?

Upgrading to InstantRails 1.0 RC1 fixed this problem for me.
