Hi,

On main project page, I'm able to display all projects and subprojects in a table format with filters on Custom Fields. However, I cannot sort project on this fields.
I can click the column title, it displays the arrow indicating that sorting is ascending or descending on this column, but the order of project in the table is not reflected accordingly.
Sorting on standard fields (Name, ID, Description) is OK.

I also tested to set the order in a saved report, behaviour is the same. Tested with following field types: Text, integer, decimal, date, boolean, none of them is working.

Environment:

Redmine version 4.1.0.stable
Ruby version 2.3.5-p376 (2017-09-14) [x86_64-linux]
Rails version 5.2.4.1
Environment production
Database adapter Mysql2
Mailer queue ActiveJob::QueueAdapters::AsyncAdapter
Mailer delivery smtp
SCM:
Subversion 1.9.5
Git 2.11.0
Filesystem

Redmine plugins:
periodictask 4.1.0

Best regards,
Yann
