[galaxy-dev] Possible bug on "Create a collection of paired datasets"

Hi, I am a computer cluster admin and I am trying to install galaxy on our cluster. I used galaxy-release_15.05 and because we need to serve Galaxy at a sub directory, e.g. irida-galaxy I modified the options prefix and cookie_path in the galaxy configuration file as follow: prefix = /irida-galaxy filter-with = proxy-prefix cookie_path = /irida-galaxy We use apache as an interface with the Following configuration: <Proxy http://localhost:9010> Order deny,allow Allow from all </Proxy> RewriteRule ^/irida-galaxy$ /irida-galaxy/ [R] RewriteRule ^/irida-galaxy/static/style/(.*) /home/irida/galaxy-dist/static/june_2007_style/blue/$1 [L] RewriteRule ^/irida-galaxy/static/scripts/(.*) /home/irida/galaxy-dist/static/scripts/packed/$1 [L] RewriteRule ^/irida-galaxy/static/(.*) /home/irida/galaxy-dist/static/$1 [L] #RewriteRule ^/irida-galaxy/favicon.ico /home/irida/galaxy-dist/static/favicon.ico [L] RewriteRule ^/irida-galaxy/robots.txt /home/irida/galaxy-dist/static/robots.txt [L] RewriteRule ^/irida-galaxy(.*) http://localhost:9010$1 [P] Everything works fairly good. Now I want to create a Dataset Pairs. first I uploads some fastaq files, e.g., a_1.fastaq a_2.fastaq b_1.fastaq b_2.fastaq c_1.fastaq c_2.fastaq then I choose: "Build List of Dataset Pairs" (See Fig-1 attached) There is a window appears on my screen with the title: Create a collection of paired datasets. Now I am able to choose a name and save the paired collection. However, once I click on "Create list" buttons I receive a error message on top of the windows: "An error occurred While creating this collection: Not found See Fig-2 attached. To be able to search the cause of error I turn on the "Browser Consul" on my web browser and notice that the error is related to the following web form post: https://newrobson.westgrid.ca:8444/api/histories/4936629215c25989/content... Which makes sense because such address do not exist. The address should be https://newrobson.westgrid.ca:8444/irida-galaxy/api/histories/4936629215c... So the prefix (irida-galaxy) is missing before /api/histories...../dataset_collection Is it a bug or am I missing something? Please note that such error does not appear when I do not use prefix in my galaxy configration.
