[rules-users] Accessing List<String> with mvel in condition

[Wolfgang Laun]

The rule should be called "B Number consists of a single character that is
not a digit".

In patterns, "[...]" means a single character, and matches succeeds if all
of the target string matches the pattern.

Try
... matches ".*[^0-9].*"
