[libreoffice-documentation] Re: Bug 122520 foreign key constraints


Hola Dan,

Noticed that Tamas Bunth checked in two patchs today regarding MySQL
foreign keys, it is marked as fixing issues in
https://bugs.documentfoundation.org/show_bug.cgi?id=122437
I wonder if it might also address the problem here.

I would give it a try with the latest 6.3 daily build in a day or two and
see if that does it.

Best wishes,

Drew
