Removing node type leaves stale data in $_SESSION['node_overview_filter']

yeah, this one is old :)

2 patches. First patch should trigger 1 fail and 1 notice. Second patch should solve the problem and clear the invalid filter in the session.

I just started to have the same issue, only with Drupal 7.12. the sequence was:

1. I had a content type called Events used for Full Calendar
2. I created a new content type called Calendar Events using Date Tools
3. Hooked that to my view in place of the old content type
4. deleted all the content from the old content type "Events"
5 then deleted the content type Events.

Now when I go to list content, nothing is listed and i get the error:

Notice: Undefined index: events in node_filter_form() (line 159 of /Applications/MAMP/htdocs/mirc/modules/node/node.admin.inc).

The site still runs and I am able to add content, but cannot filter at all. would the above patch work for drupal 7.12 as well? Any ideas what casued this?

thanks.

Please keep this on 8.x where it needs to be fixed first. If the patch applies to 7.x it will also remove the notice, but let's wait first what other people think of the patch.

I'm just confirming that I did see this message after deleting a content type on 7.14. But, in my situation, the filters seems to be working again and the message is gone.

Changing title, will re-roll in a minute.

Good to see you can't delete content types anymore when there are nodes :)

This is not valid anymore in D8

Patch no longer applies. They are all for D8 so would need to be rolled for D7.
