This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
steps to reproduce: 1) Have an empty user task list 2) Create "first task", then "second task" and make "second task" dependent on "first task" 3) create independent "third task", add to the end of list 4) make sure first task is expanded 5) sort tasks according to priority, higher priority on top (should do nothing, priorities are the same for all tasks now) 6) boost priority of third task tree become corrupted in following way: third |---second +first correct result should be: third first |---second Workaround: toggle priority order and tree will correct itself
I think the -sorting- is what's causing problems here. I've also seen and heard reports of "invisible" tasks when sorting is enabled. I suspect the problem is in the TreeTableView - since turning sorting on and off has nothing to do with the tasklist module (it's done transparently inside the treetable). But I will investigate/reproduce this first and make sure before reassigning to openide/explorer.
Yes, I'm confirming, invisible tasks appeared on my machine too. And yes, it looks like TreeTableView, it seems that data stored on disk are always right during the steps I mentioned.
