On my instance of myExperiment (created this morning using the latest
version of the code). I can upload a workflow, view the workflow page
without issue, but if I navigate away from the page, then return to it
again (not using the back button in the browser) I get the following error:
"undefined method `contribution' for #<Workflow:0x7ff60c96da20> (full
stack trace below)"
This error then continues to occur when I try and view the same, and
certain other workflows* until I restart the server.
*The three test workflows that throw the error were all created from
this t2flow file:
http://www.myexperiment.org/workflows/16
I have a fourth test workflow using this SCUFL file that doesn't
trigger/react to the error:
http://www.myexperiment.org/workflows/72
This doesn't happen for Groups or Files.
Any ideas?
