hi, I'm testing JasperETL and I found (maybe) a odd bug/problem. I have 3 .xls files in entry and I want to obtain one .xls file with a concatenation and selection. http://img120.imageshack.us/img120/4976/pb1tl6.th.jpg http://img241.imageshack.us/img241/6731/pb2jn8.th.jpg As you can see on these pictures. I have 464 rows then 494 rows. between the 2, I don't do anything (only push "Run") Data in my 3 xls files haven't change. On the last picture, you can see the treatment that I do. http://img412.imageshack.us/img412/1139/pb3vd4.th.jpg I can send you the 3 files, if you want. I thank you for your futures answers and I apologize for my bad frenchy speaking Guillaume Post edited by: test.guillaume, at: 2007/02/20 14:08 Post edited by: test.guillaume, at: 2007/02/20 14:09 Post edited by: test.guillaume, at: 2007/02/20 14:11 Post edited by: test.guillaume, at: 2007/02/20 14:12
