Missing dependency on Panels in Features with one page in Page manager

Do you have the page manager module enabled? I've never seen that error before, and I'm unable to reproduce it. Please upgrade to the latest branch and reopen if this continues.

Hi, I'm getting a similar error trying to enable a features module. I'm up to date on code versions. Any fixes?

I enable all the dependent modules:

The following extensions will be enabled: ctools, token, path, page_manager, strongarm, diff, devel, backup_migrate, jquery_update, advanced_help, pathauto, favicon, module_filter

The panels_display class is in panels.module

The only way this can happen is if something that requires Panels is being loaded while the panels module is disabled. It's possible there is a failed dependency but for whatever reason, the fix would be to enable Panels module.

Thanks Merlin! That worked.

Hi,

I made a features with one page in page manager. The front page of my site with some static panels.

When I exported the feature and imported, I got the above error. This is because "Panels" wasn't installed.

Enabling panels before enabling my features module is the workaround.

Thanks!

Mike

Closing this for lack of activity. Please re-open this issue if you can reproduce it in the latest version.

Hello there. I hate to reopen an issue, but I am getting exactly this same error. I had to go to the database to enable the panels module. Then it worked like a champ.

Same solution for me. Except that I enabled it through the UI.

Unfortunately Features itself can't do anything about this. Dependencies are handled by the modules that implement the export functionality. In this case you need to report this to the Panels or CTools issue queues. (Page Manager is part of CTools).
