Bug in admin interface for parameter remove-message

Hello,

From the latest user guide
http://www.kannel.org/download/kannel-userguide-snapshot/userguide.html#AEN926
remove-message "Removes the message with the give id (an UUID) from
the local storage
subsystem."

But this is not working.
I need to remove specific message from kannel queue and i am testing it by
using fakesmsc.

Here is my redmine link:

Thanks
Kirti
