Bug 140705 Insert group does not work properly when cache preference is set
When cache preference is set, insert group does not work properly. Steps to reproduce problem: In Birt report designer: New a report design, data source, data set; Insert a table, drag several columns into table; Set cache preference for data set: check checkbox "Cache dataset data for report view"; Select "Cache and use first [] rows"; Enter '100' as row count. PREVIEW report; Insert group, Preview report again ---> problem happens: only header line will show up. All details are missing. Sample report is also attached.
