Hi, I'm altmost new to Jasper studio. I have a strage experience: I played with 6.5.0 version and today I installed the 6.5.1. The big problem is that when I create a new JSON adapter from local file I don't see any data (I see the fields). It works fine for "read fields" but I don't see any data on "Data preview" tab. Also when I add a field in the detail section of the report looks fine, but on the preview I can see only a null entry. T tried many time, just noticed that it worked perfect yesterday, also the JSONQL queries, subreports everything... To avoid any confusion I used the nordwinds JSON file from the samples project. I tried both windows and mac versions. I spent altmost the entire day looking for a solution, anybody has any idea? I'll look to attach printscreens if anybody interested to help. Thanks, Geanni
