When adding a sortField tag to my Jaspersoft report, it produces a strange behaviour of the groups display. More precisely scheme is :
display some imamges
some static texts
display the dataset
Detail section display the dataset sorted, so it is okay, but the group 2 will be displayed over all pages, even where the images of group 1 are displayed. I think it is a bug of the sortField tag. If it is not, please explain to me the way to do it right.
