The example doesn't remove the content type when you disable and uninstall.
Ah. I had used Features to export the node type. I thought for sure it would have handled cleaning stuff up.
I'll add in the cleanup code.
So how does one remove the flexslider_example content type? The drupal interface does not allow to remove it, probably because it if provided by features?
Here is a patch that will delete all the Flexslider Example nodes and delete the FlexSlider Example content type.
This is a bug with core and Features. But we can include this for now until that gets fixed.
But can you update the patch to use node_delete_mulitple instead?
It also may need to run on hook_disable and not hook_uninstall. But you'd have to double check that.
Committed a fix.
Automatically closed - issue fixed for 2 weeks with no activity.
Just passing by... noticed that the original request asked to remove the content type but the committed patch only removes the content of that type. The patch from comment 3 does include the deletion of the content type, but looks like that left out of the commit (I tested that and it worked for me).
The easy way:
1. go to /admin/content/ and delete all "flex_slider_example" nodes
2. go to /admin/structure/types/manage/"flex_slider_example"/delete it will delete it
Fix for [#1840288] Added entity field query during hook_uninstall().
