paging returns an error using next_page - posting workaround
Reported by cyberkid81 | May 9th, 2010 @ 12:54 AM
When using the next_page function, this error is showing up and
the program exits:
/usr/local/lib/ruby/gems/1.8/gems/scrubyt-0.4.1/lib/scrubyt/core/navigation/fetch_action.rb:39:in `restore_host_name': uninitialized class variable @@original_host_name in Scrubyt::FetchAction (NameError)
I modified this file: /usr/local/lib/ruby/gems/1.8/gems/scrubyt-0.4.1/lib/scrubyt/core/navigation/fetch_action.rb
I set @@original_host_name to nil and saved. That's it. It appears fixed. See the code segment below.
module FetchAction
@@current_doc_url = nil
@@current_doc_protocol = nil
@@base_dir = nil
@@host_name = nil
@@history = []
@@current_form = nil
@@original_host_name = nil #add this line to fix next_page error
