I would like to ask if jasperReport is support subreport inside subreport? My situation is 3 level of report. Main report is a paper, second level is a list of questions, the third level is a list of answers. Therefore, each question have a list of answers.
In Main report + the subreport of question, I can use JRBeanCollectionDataSource for passing the list of question. However, I don't know how to merge the subreport of question with the subreport of answer.
In fact, in my code, I pass value for the first subReport "Question" by questionDatasource which is a JRBeanCollectionDataSource. The key is from that qestionDatasource. How can I get value from the JRBeanCollectionDataSource? If not, I can't get the value of answer by the key.
