Hi guys,

Could anybody provide me with a guide/demo/tutorial about Jasper reports in Odoo V8?
I found the source code for V8 here: https://github.com/JayVora-SerpentCS/Jasperv8
The module installed without any problems and under settings > Technical I have two new items for Jasper reports.
From here on I am clueless though. If I understand this correctly you make an XML which specifies the model through 'Create Data Template'? But what then?

There are no tutorials or guides to be found and especially not for Odoo V8. Could anybody help me out here?

Update: I found out there is demo data in this module. When you create a new database with the option for demo data ticked on you can see this under settings > Users. This directly throws up an error when you want to print though:
