The earlier release of uniCenta oPOS 3.02 (07:00GMT today) had a fail across all
Reports. This is caused by Jasper iReports introducing a new but not very clearly
documented upgrade to their iReports Designer.
Quite rightly this has caused a real stink and there are some very unhappy people out there, me included.
Look here for example: http://community.jaspersoft.com/ireport-designer/issues/5784
If you Downloaded uniCenta oPOS in the last 12 hours (4 Dec 12) you will find you are unable to run reports and receive an error message about "uuid...."
I have reverted to an earlier version of the reports which fixes the problem.
You need to download the latest version of uniCenta oPOS v3.02 - uploaded @ 18:15GMT 4 Dec 12
