Invoice copy problems

We have found bugs during copying invoices.

  1. You can change the creation date in dialog, but new invoice contains date from origin invoice.

  2. Custom fields are not copied to new invoice.

I have exactly the same problem in my version 1.5.8 and another one

  1. The item_product_unit are not copied for my article


See ticket

But custom fields and item units are correctly copied, can’t reproduce any problems with that.
