The issue you're seeing is actually related to improper initialization of the workflow parameters index in the special case where a particular parameter is only used in a rename action and not in a tool step.  This is fixed in revision 5400:6cacf178a129.

Hi all,

I noticed a new problem with our local Galaxy (recently updated),

but found it happens on the public installation too.

I can edit workflows, and create run time parameters like ${Name}

or ${Name with spaces}, but when I come to run the workflow I get

an error:

Server Error

An error occurred. See the error logs for more information.

(Turn debug on to display exception reports here)

e.g. This trivial example takes a FASTA file, does a minimum length

filter, and tries to rename the output to a run time parameter string:

http://main.g2.bx.psu.edu/u/peterjc/w/test-workflow-filter-fasta-min-length-10

Is this a known issue? I couldn't find a match on the bitbucket

tracker.

Thanks,

Peter
