Add a note on a folder

Question

When  I've tried the following syntax to add a note on a folder (and not on subelements on folder), this lead to a NullPointerException (cannot add the error because of max allowed characters).

If I associate my note on "titi" and "tutu", this works fine.

Does anybody know another manner to do that?

Thanks

Note "my note" as My_Note

package "TOTO" {
  folder "toto_files" as t_files{
    [titi]
    [tutu]
  }
}

t_files .. My_Note

The example is working fine for us :

Which version are you using ? Maybe you should upgrade ?
