Description Ivan Furnadjiev CLA 2012-11-12 07:52:25 EST 
Start Controls Demo -> Table Tab. Check VIRTUAL and "Update virtual items delayed". Change "ItemCount" to 200 -> scrollbars are updated but not the items. Start scrolling with the mouse -> "..." items appear on the bottom. Probably related to UICallBack rework.

More over if you navigate away from the Table tab after this weird behavior you got:

Change the component to Demo. When using Jobs without the workbench (JobManagerAdapter) we need to activate/deactivate the UICallBack ourselfs.
Comment 3 Ivan Furnadjiev CLA 2012-11-12 08:17:05 EST 
Same issue exists in Tree Tab.
Comment 4 Ivan Furnadjiev CLA 2012-11-12 09:33:30 EST 
Fixed with commit 266903170b44f3265c35af0e880d2a02c2fa6e3b.
