Hello,
In the View Issue screen, the structure doesnt appear with the version 5.1 of Jira.

It should be up activy like in Jira 4.2.4.
- The issues are in structure (it work in 4.2.4 and its a same data)
- The permission are anyone so no restriction. In the log I have this :
WARNING: A servlet POST request, to the URI http://xxx.ubisoft.org/jira/rest/structure/1.0/data, contains form parameters in the request body but the request body has been consumed by the servlet or a servlet filter accessing the request parameters. Only resource methods using @FormParam will work as expected. Resource methods consuming the request body by other means will not work as expected.
Thanks
Martin
