Re: [galaxy-dev] Error: Unable to cleanup job

Peter, I want to follow up on the hidden dataset issue. You have a step in your workflow with a Hide Dataset Action and even though the job fails, the dataset still gets hidden? If this is what you're seeing, it is a bug and I'll fix it. This is not the intended behavior. Lastly, and you might have already found this, you can toggle the display of hidden datasets in the history panel through the Options menu at the top. Dannon

I worked out what was wrong - an early step in my saved workflow was missing a parameter. However, the output from this step was being hidden -- so I was not able to read the error message.
