Hello John

Thanks for taking a look, and for the explanation. It's useful to know that it's not something intrinsically wrong with what I've been doing, and I'll work around it for now. It's good to know that it's targeted for a fix at some point, even if it doesn't make it into the next release.


Thanks again, best wishes

Peter

Sorry this has been sitting in my inbox for a while - because I wanted
to try to fix it before the next release but I don't think it is going
to happen.

Generically - it doesn't surprise me that Galaxy can handle certain
parameters changing between versions but not conditionals - they are
handled in a much more complex manner. I have updated this
(https://trello.com/c/INCluhxP) Trello card to reference this problem.

Sorry I don't have better news right now.

Dear all

One of my users has encountered a problem with extracting a workflow from a 
history in our local Galaxy installation (tag latest_2014.08.11, changeset 
14342:db520d154716).

The history was created with a version of a local tool which has since been 
updated, and the extraction page warns that the newer version of the tool will 
be used for those datasets i.e.:

Dataset was created with tool version "0.0.4", but workflow extraction will use version 
"0.0.7".

However when the extraction is run it fails immediately: the user sees the "Internal 
Server Error" page, and in the log I see:
=====

   group_values = values[input.name]
KeyError: 'platform'
=====

'platform' is a conditional parameter that was introduced into the tool between 
the two versions. It looks like when tying to use the newer verison of the new 
tool, that the new parameter is not getting picked up. Is this expected 
behaviour?

(Btw I've seen a similar issue i.e. the "KeyError: 'platform' exception when I 
have the two versions of this tool installed from a local toolshed, and try 
switching between to the newer one from the older one.)

Any help or suggestions are greatly appreciated.

Many thanks

Peter
