I'm trying to build a report using a json data feed - while I can access the first level of data within the feed I am unable to access any second level data. I'm not entirely sure I am using the correct terminolgy so I have provided a screen capture of the data source record tree (see below). What I'm trying to do is auto discover the field under record.add_outlet.record tree node, when I hit next the field list is empty.
This is a data source/set for a table within the report - ultimately I would like access the sub levels from a sub report.
I have tried to find a solution using various forums and can only find reference to solutions involving net.sf.jasperreports.engine.data.JsonDataSource and subdataSource which I'm strugging to understand yet alone implement.
I would appreciate any assiistance that could be provided. Should I continue to try and understand the JsonDataSource subDataSource approach or is there alternative solution?
I am using Jaspersoft Studio 6.0.3.
