This is driving me a little crazy.

Server - phusion passenger & nginx, running in production mode.  
Extensions installed :

drag\_order  
file\_system\_resources  
mailer  
page\_factory  
page\_parts  
paperclipped  
rbac\_base  
rbac\_page\_edit  
settings  
share\_layouts  
tags  
wym\_editor\_filter

After I restart one of my sites, visits to edit pages in the admin are  
met  
with the following :

ActionView::TemplateError (undefined method `include?’ for nil:NilClass)

I’m stumped. I thought it was the version of will\_paginate I had there  
(2.3.14) so I downgraded to 2.3.11 thinking that would help, and it  
didn’t.  
Has anyone run into this before or have advice on how I might go about  
tracking this down.

Thanks!

- Joel

I should also add that after about 30 minutes or so - things start  
working.  
“Magically”.

I am so confused right now.

I guess I’m not the only person this has happened to :  
[http://groups.google.com/group/radiantcms/browse\_thread/thread/9148b7ba9af126ee](http://groups.google.com/group/radiantcms/browse_thread/thread/9148b7ba9af126ee)

To clarify it a little more - this is only happening right after I  
restart  
by `touch`ing tmp/restart.txt. As previously mentioned, after a little  
while it sort of “kicks in” so to speak and the error stops occuring.

And to answer Jim’s question from the other thread - these are the gems

I’m just stumped as to why a line like

@page.parts

would cause "ActionView::TemplateError (undefined method `include?’ for  
nil:NilClass) "
