There is some issue with WBS column, when we delete the task sometime WBS code is not right.
On bryntum site with advance sample I have deleted some task and drag and drop rows then one task that shows parent task but WBS is at same level with other task I am attaching screen shot for your reference.
I have downloaded the sample and when I delete some tasks then even sometime link are not deleted from chart window plus there is issue with WBS code when deleted some tasks.I am attaching screen shot for the same.
Please have a look into this problem.
