I’m looking to get Shards working and I keep running up against one
error that I’m unable to find documented anywhere or fix. Any help here
would be killer. 
Here’s the error:
undefined local variable or method `children_class’ for
#<#Class:0x26cc684:0x26cc65c>
It seems to be choking here:
vendor/extensions/shards/app/views/admin/page/_node.rhtml:1:in
`_run_rhtml_47vendor47extensions47shards47app47views47admin47page47_node46rhtml’
I only get this on admin/pages. The rest of the admin interface works
fine.
