Erroneous behaviour of "Duplicate Invoice" feature in 2.4.2

[DonM]

Christian,

Thanks for the detailed explanation of how to fix this issue.

I get this same error message whenever I create an invoice, using ver 2.4.0. I suspect this is because I always have a line on my invoice that has no charge on it, but I haven't tested to confirm this.  Is this related? Do I need to go back and fix my previous invoices in this fashion?

I raised this issue on this list back on Jan 15, but did not receive any response.

Thanks for your help,

Don

> "<invoice:id>01234</invoice:id>". You should notice that the file contains

>    <invoice:currency>
>      <cmdty:space>ISO4217</cmdty:space>
>      <cmdty:id>USD</cmdty:id>
>    </invoice:currency>

> 6. Save the file in the text editor and open it again in gnucash. (Feel free
