BUG: multiple select using predefined list

It is still not possible to "null" a field that uses a predefined list for a multiple select field.  This has been discussed extensively and worked fine on D6.  Alex did a patch that fixed the search portion of this problem, but the join form issue remains.  When the patch is applied, the actual words "not selected" or "not specified" will be selected every time a user edits their profile - an unacceptable solution.   Since the "discussion" below, several new members have posted independent threads reporting this problem.

For some reason, the ticket was closed, but this has not been fixed, and I consider it to be a central database function.  Could someone with access to trac please reopen this ticket - this has not been fully fixed yet: http://www.boonex.com/trac/dolphin/ticket/1627

Bug is listed as "fixed" in Trac, but it has not been fixed: http://www.boonex.com/trac/dolphin/ticket/1627 As discussed, it does not work with multiple select fields.

This issue has been improperly listed as "fixed" in Trac - this has not been fixed.   Some patches Alex applied can make it partially work, but it still doesn't work properly, and still comes up here as people try to create some more advanced search functions.    I have written both my Agent and Alex about this and again request that this issue be addressed.
