We have been trying to use OpenProject and had everything working and then sometime around the time of adding different types of Work Packages we started getting the following error.

NoMethodError (undefined method `position’ for #WorkPackage:0x000000095e9e40):
app/controllers/work_packages_controller.rb:144:in `create’

I’m a ruby newbie and so I have no real idea what to look at in terms of troubleshooting this. I see position throughout the code, but I’m not sure why this would be coming up. Also we had been able to post work packages just fine and are able to create other types of content on our openproject instance but not this.

Here is the complete log for this. Any help would be appreciated.
