When a @Rooplural is added to an entity the "list all entity" option from the navigation menu of the app isn't displayed, that means that the corresponding item in menu.jspx for list the item isn't added. This seems to be a Roo issue since it happens with recently created projects where no configuration file was changed manually.
In the original thread on the forum I reported the issue for version 1.1.3 but recently I confirmed that the 1.1.4 version has the same problem. I don't know if the usage of @Rooplural was changed in recent versions but in the documentation I don't found anything.
Thanks for all, regards.
