[webgen-users] custom menu plugin not working in 0.4.4

I was pushing out a new version of a site I have that I think was last
generated with webgen 0.4.1.  Since my gems are updated to 0.4.4 I''m
getting
this error when running ''webgen''.  I''ve reverted back
to 0.4.2 and that is the
version where this custom vertical menu plugin starts breaking.  So I''m
not
sure what has changed to cause this.  I get this error on webgen 0.4.2, and
0.4.4, but not on 0.4.1 when using a custom site plugin.

Any hints?

proj/keybox/webgen/plugin/jjh-vertical.rb:27:in `load_plugin'':

It may be possible that the plugin system tries to load your plugin  
before MenuStyle/Default. Did you use the ''load_plugin'' at the
top of
your plugin file? The following line should be at the top of your  
plugin:

   load_plugin ''webgen/plugins/menustyles/default''

If this does not solve the problem, I will investigate further!

Best regards,
   Thomas

Yup, that''s there... here''s the basic layout of the plugin 

load_plugin ''webgen/plugins/menustyles/default''

module MenuStyles

  class JJHVerticalMenuStyle < MenuStyles::DefaultMenuStyle

  infos( ... )


  register_handler ''jjh-vertical''

  param ...
  param ...
  param ...
  param ...


  def internal_build_menu(src_node,menu_tree)
  ...
  end

end

thanks for taking a look.

enjoy,

-jeremy

Okay, I have tried this out and realized that I have seen the problem  
before: it is the way webgen loads plugins. It loads custom plugins  
in a slightly different way than plugins shipped with webgen. I  
didn''t realize this when coding the plugin system. One thing that  
makes problems is when you define your class inside a module. So if  
you remove the top level MenuStyles module and declare the  
JJHVerticalMenuStyle at the top level of the source file, it should  
work. Another way is to include the top level environment in the  
module, something like:

WEBGEN_ENV=self

module MenuStyles
   include WEBGEN_ENV
   ...
end

This behaviour does not occur in the current development version of  
webgen since their "all plugins are equal".

Regards,
   Thomas
