[ckan-dev] package_update throws error when adding extra field

Mon Feb 4 09:23:49 UTC 2013

I'm using 2.0a currently. I've mocked my controller and put it on GitHub: https://github.com/FabiApfelkern/ckanext-custcon

Thank you very much!

That's interesting. What version of CKAN are you using? And can you send us your CKAN extension, or a mock extension that demonstrates the error (e.g. post it to github)? That would make it easier for me to reproduce the problem and investigate.
