Redmine Gantt Chart Sorting
I believe I came across a bug in my Redmine instance. When I create issues->features and view the gantt chart, it does not always sort the parent/child relationship correctly. It displayes child features uner the wrong parent. However, I am sure that I entered in the data correctly for the given issue because when I do into the details of a particular issue, all of the listed "sub tasks" are correct. I have verified this in multiple browswers and multiple computers.
Assuming that it is a Redmine bug (not specific to TKL) then there is a good chance it has already been fixed in more recent versions (a quick google seems to suggest that it is an upstream bug, but I can't be sure as I didn't spend a lot of time reading). Also I notice that there is a "better Gantt chart plugin" for Redmine, but I'm not sure how (or even if) that is relevant (just found it when googling and thought it may be of interest).
I'd try updating your Redmine instance and then check if the bug still exists. There is a thread here that discusses upgrade and even has a patch. I would be careful that you have all your data backed up first though (and test your backup - don't just assume that it works as it should). Another thought, is just create a new Redmine VM and do a quick test to confirm the problem, then upgrade Redmine (perhaps with the patch above?) and test again. If it is no longer a problem then either upgrade your existing system, or migrate your data to a new instance.
And worst case scenario, as Redmine (and TKL itself) is open source, you are always free to fix bugs yourself if you wish (or pay someone else to do it if you don't have the time and/or skills).
