Redmine

Situation:
You have a custom field of the type "List".
In your list are entries which run like "entry" and "second entry".

While "entry" will generate a link with the "Link values to URL" using value, "second entry" will not be clickable.
If I'd use "second+entry", it'll very well work though.

Suggested solution:
Redmine is to parse blanks and substitute plusses for them automatically before outputting the link.
It will present the list entry in the custom field as a clickable link.
