I am working on a system to manage my invoices in books from creator. I need to be able to either create the invoice with status "sent" or be able to convert to "sent" from the default "draft"... 

when I create the invoice from creator, it always creates it as "draft" regardless of what status I put in the parameter. Probably this makes sense as "sent" implies an email to the customer has been actually sent... just need to understand how to manage this process from creator...

thanks for any help
