When a user tries to see the tasks 'Done' from bonita portal the response takes too long to arrive. About 2-3 minutes. At first i thought there were no 'Done' tasks but when i waited for some more they finally appeared. The point is that these 'Done' tasks belong to cases that have been archived and some of them are already 4-5 months old so they are of not of much interest.
I thought of removing these cases but i found no way to do this from the portal UI, even as an admin.
Any ideas how i could solve this problem?
