Cannot update ticket_type with no name

[bladezibit@…]

Trac allow addition of Ticket Type named " " (without quote).

When I try to remove a Ticket Type named " " (by clicking the remove button), the system fails silently and nothing happend (the category is still there).

When I try to set the Ticket Type named " " as default, the system fails silently (the old default Ticket Type is still the default).

If I try to change the Order of my Ticket Type, I get the following exception:

Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/trac/web/main.py", line 406, in dispatch_request

AssertionError: Cannot update ticket_type with no name

Trac should not allow addition of Ticket Type named " " if it's not a valid name...

Thx,

I'll check if this still happens on trunk.

Any news about this ?

On trunk it is already not possible to add a ticket type (or any other select field) with only whitespace in the name, neither with trac-admin nor in the admin panels.

I have fixed a few inconsistencies in whitespace normalization in [8399], changed the AssertionError when adding or renaming a field value to whitespace-only into a slightly more user-friendly TracError, and fixed the admin panels to display e.g. "Invalid component name" instead of "Component already exists" if the name field is empty (and the same in the roadmap).

If you had already added a whitespace-only value in the past, you will have to remove it with some SQL-fu, e.g.:

DELETE FROM enum WHERE type='ticket_type' AND name=' ';
