Styles will not printed after accessing the report via REST API

Hi folks,

if I deploy a report which uses a style template everything is fine. I can execute the report inside the jasperserver and all styles like the font properties are printed correctly.

But, if I try to access the report via the REST_v2 Interface, I get the report as PDF without the custom styles from the template.

Does anyone have a sugggestion?

Thanks for any help.

Best Regards 

Florian
