I followed John’s advice to make tags global instead of fiddling with  
behavior inheritance, but I ran into the following problem:

I define my tags in a class that looks like this:

class Behavior::Base  
define\_tags do  
…  
end  
end

Everything is fine as long as the page on which I use the tags has no  
behavior. But when I assign Sean C.’ Commentable behavior to the  
page, I get a “undefined tag” message when visiting it.

Any idea what goes wrong here? The Commentable behavior extends  
Behavior::Base, so if I in turn extend that one, pages with the  
Commentable behavior should profit from it, or am I missing something?

Thanks for some hint in this!

Wolfgang

I think this is a problem with which plugin is being loaded first. The  
way the define\_tags code works if you inherit from Behavior::Base and  
then define tags on Behavior::Base the subclass won’t get the new tags.

The fix would be to make sure that your code is required before the  
commentable behavior.

I just discovered that exactly the same problem is already being  
discussed here:

[http://www.ruby-forum.com/topic/80345](http://www.ruby-forum.com/topic/80345)

Sorry for the unnecessary new thread, I’ll join the discussion on the  
other one.

Unfortunately (imho at least, as the Rails core team obviously is under  
a different opinion), there is no way to configure plugin load order in  
Rails. You have to resort to renaming the plugin directories like that:  
“01\_…” to “[n]_…". Because plugin directories are parsed in  
alphabetical order, the "01_…” plugin will be loaded first etc. I  
renamed my behavior directory that way and now everything works like a  
charm.

Cheers,

Rails’ conventions strike again.

Migrations imperatively work the same way (ordered by number-prefixed  
directory names).

That’s sweet knowledge. Thank you.
