Dear Galaxy developers, I am interested in adding a download link to the “Download or Export Workflow” page of a workflow. I am able to add the link through the files in the templates directory and correctly add the necessary API functions in the lib/webapps/galaxy/controllers/workflow.py file. I wanted to ask for some help in figuring out what I might be missing when I try to download a file when I have load balancing feature activated. The page looks something like this: Download to File Download workflow to file so that it can be saved or imported into another Galaxy server. <https://dev.globusgenomics.org/u/arodri7/w/workflow-1-for-asms-2016-workshop-imported-from-uploaded-file-1/json-download> New Test Download ( test file) URL for Importing to Another Galaxy This workflow must be accessible before it can be imported into another Galaxy. <https://dev.globusgenomics.org/workflow/sharing?id=a728237e0d32bb8c> As you can see I added the “New test Download” link. I have added and tested the function which gets me the information about the workflow I want correctly. For now it’s just a “hello world” string. When I don’t use load balancing I get the contents I want downloaded to the file correctly. However, when I activate load balancing, it only downloads an empty file. I can print the contents of the test download file to the galaxy log, but as I said nothing gets printed on the actual file. Is there some javascript code I also need to add for this functionality that I might be missing such that the download works with load balancing? As I mentioned I do get a proper download when load balancing is not activated. BTW, all other existing download links work properly with both load balancing and no load balancing. Thanks, Alex
