Dear All,

       I' m working with jasper report to customize all openerp reports. I succeeded  to add invoice lines  using OPENERP_RELATIONS =['invoice_line'], but i failed to add tax lines. After days of search i found that the unique way to do it

is to add a subreport. I followed the steps but unfortunally the subreport works independently but it shows nothing in the main report. I'm really blocked and i need your help. Does anyone have any suggestions on how I should handle this?

Kind Regards
