Task bar editing doesnt' update task dependencies


I just noticed that when editing a task bar, the task dependencies aren't updated.

actionComplete(args) {
   if (args.requestType === "save") {
      for (let i = 0; i < args.modifiedTaskData.length; i++) {
         //api calls and other stuff

In args.modifiedTaskData there is just the task I am editing and not the depending tasks.

My Syncfusion version is 20.4.52, with a previous version (20.3.48) this worked.

I've checked the changelog and with version 20.4.48 it seems that has been fixed:

  • #I430365 - Child tasks not updated after updating parent task predecessor has been fixed.

I think I'm still facing this issue.


If I drag and drop "gggg" to the 4th of January:

I get this:

In the previous versions I would have got this result:


Could you please verify this?

Thank you in advace.

Best regards,

Matteo Messmer
