Hey Sean,  
What’s the suggested version of radiant to run with the suggested  
version of  
the templates extension.

I tried [GitHub - radiant/radiant: Radiant is a no-fluff, open source content management system designed for small teams.](http://github.com/radiant/radiant/tree/master) with  
[GitHub - seancribbs/radiant-templates-extension: NO LONGER MAINTAINED. See http://github.com/avonderluft/radiant-templates-extension](http://github.com/seancribbs/radiant-templates-extension/tree/master)

and am running into lots of problems…

for example…  
what javascript file defines the “Behavior” class?

and…

You have a nil object when you didn’t expect it! The error occurred  
while  
evaluating nil.filter  
…  
25: %span#filter-type= filter.filter\_name  
…  
app/helpers/admin/pages\_helper.rb:10:in `filter' app/views/admin/pages/_popups.html.haml:25:in `\_run\_plugin\_47app47views47admin47pages47\_popups46html46haml’  
…

Looks like the templates extension didn’t set filter on some page part  
perhaps? If this is required why isn’t there a validation for it.

Step away for Radiant for a year… and everything changes

Jacob

Jacob,

It should work on 0.6.9. Behavior comes from lowpro.js, which I use all  
over the place. My apologies if it’s not in there. I’m not sure what’s  
causing that filter error, unless your Radiant version is not 0.6.9.
