Birt Data Set script method "Fetch" returned null fetching 2nd row of table [message #1782048]

Hi,

I am new to Birt reporting tool and trying to learn the scripted data set. My requirement is simple - to fetch data from spring service method and show it to the table. Currently I am getting ''Data Set script method "Fetch" returned null' while fetching 2nd row of table in other word, the first row is successfully being fetch and I can see it in the report with data. My data list contains 5 or more list of java objects. Unable to figure out what I am missing(rptdesign is attached). Tried putting the content of initialize method in data-set's open method but still the output was same. Stack trace is attached with the post. I need some other operations like adding aggregation/dynamic column to the table so I fetched the data in initialize method instead of data-set's open method.
