As there is a refresh meta (<meta http-equiv="refresh" content="30"/>) on the project group page, it can leads to errors.
- Go to a project group page
- Edit the group and save
- The url is now something like: saveProjectGroup.action
- after 30s, the refresh meta starts => Error 500
This system works fine when user stays on projectGroupSummary.action page but if the url changes, there is an error as we call an action without any information.
