When using the Gantt chart plugin, deleting doesn't work
|Reported by:||anonymous||Owned by:||coderanger|
When you install the GANTTCHART plugin, the creation of four custom fields is neccessary, two of them are of the type date, i believe. however, the TICKETDELETEPLUGIN is not able to delete dates from those fields. The error message is that "none" is not a valid value.
