Thanks Kalmenchia!! So basically if I am calling a report like report_sxw.report_sxw('report.prov', 'product.product', 'addons/sim/report.rml',parser= folio_report) then under the .rml file the object will be 'product.product', right? Thats "automatically" or I have to 'pass' the object somehow? I am asking this because for some reason when I create dynamic reports I always get a damaged PDF so I am trying to debug everything to understand whats wrong. Thanks again for your time.

yes , as long as you do this right , 1. the report defination py file, rml are in getting the right model ,eg yours , you already called the "product.product" , so it will get from product model . When u get a corrupted pdf , it has many reasons , perhaps , your RML template is not correct , and the best if you are going to use the RML's way then you have learn RML syntax or ELSE , there are a few options available , http://blog.instant-erp.com/2013/05/the-7-seven-options-of-reports-in.html and more is coming i believe !

Thanks again. I understand RML syntax pretty much. I am testing with a super simple report and as soon as I remove the "dynamic" part from the RML file, for example "<para style="Standard">[[repeatIn(objects,'p')]][[p.name]]</para>" it works, thats why I am trying to understand what can be so wrong with that line that is producing a corrupted PDF. If you have any idea please let me know. Thanks again for your help!
