[ckan-dev] PluginNotFoundException even though it works.

[Rachel Knowler]

Hi Henrik,

I've also been getting error messages like those when writing plugins 
recently. I guess you have seen this page, which was almost all I could 
find when searching the internet for similar issues: 
http://trac.ckan.org/ticket/908.html. It seems that the problem might be 
something to do with the Apache wsgi script, but I don't know how or why!

In my case, I narrowed the cause of the problem down to the plugin 
getting the group_list API action function 
(http://docs.ckan.org/en/latest/api/#ckan.logic.action.get.group_list). 
This was strange, because it was properly using the plugins toolkit to 
get the action, and because elsewhere in the plugin the actions 
group_show and group_create worked fine. I ended up working around this 
in the plugin.

Can you try eliminating API functions from your plugin to find out if 
any of them are causing the problem?

Cheers,
Rachel
