Conflict with Ticket Validator Plugin

[sdw_1979@…]

Hi, i've a TRAC 0.12 and i've installed your (great) plugin, it's ok and awesome but i've a problem with the option "date_empty = true". I've configured two date fields, "due_assign" and "due_close", to identify the start and the finish of a ticket life, the "due_close" is made required by a plugin (​http://trac-hacks.org/wiki/TicketValidatorPlugin) so when a ticket state become "Closed" , the "due_close" field becomes required. The problem is that if i choose to use the option "date_empty = true" , i can leave an empty date even if the ValidatorPlugin is working and if i don't use the date_empty, the field is ALWAYS required and i don't want to insert an open date (31/12/9999) to force the validation, i want the user to insert a true date only AFTER the closing of the ticket. I hope you understand my explaination, sorry for my english.
