I'm running FA 2.2 RC. When selecting Recurrent Invoices then the dropdown for template is empty. This is the case on initial company (with FA demo data) and on my own company.
Currently the demo 2.2RC is not working so I cannot double check.
Very often I have recurrent invoices for which the first one is different. The first one includes for setup kosts. With your template driven recurrent invoices I hope to find a way to make recurrent invoices based on templates (so not on exisiting invoices). Then I can make one first invoice and prepare a template for the recurrent ones.
Anyway, still I first need to have the template dropdown filled and as far as I was able to investigate I suspect a bug.
