I am seeing a problem with the display of frames in 3.7.0 (CE).
A very simple dashboard -- I am using the Foodmart sample data to drive this demonstration of the issue.
Two frames, the first contains a bar chart, showing the stores with the smallest number of employees, and the second contains a list of the newest employees.
This works fine in iReport.
Deploy to Jasperserver and look at it there, and there are display problems with the second frame.
This problem varies - in some cases, the frame doesn't display at all and neither does the contents, in other cases, the content displays, but the frame doesn't.
However, view any of the other display modes (PDF, Flash, RTF, etc.) and the display is fine.
