Our state of the art Gantt chart


Post by arcady »

Ok it seems I've finally managed to boil the test case down. Here is a ticket for the bug: https://github.com/bryntum/support/issues/3031
Thank you for the feedback!

Hi!

I'm updating to Gantt 5.0.3 and I'm revisiting previous issues. Here I ran the test cast with the updated Gantt component. Here are the updated steps:

  • Run the demo.
  • Expand the tasks in row 73
  • Double click on the predecessor arrow of the task of row 73. That'll open the dependency editor.
  • Hit delete.
  • Now drag the task in row 73 just slightly to the left, like 1px, so it gets a constraint date.
  • :!: (Still happens) Notice the dates of the some subtasks have changed.
  • Edit the task in row 74 (the milestone), go to the advanced tab and hit the X in the constraint type box. (don't save just yet)
  • The dates of some of the subtasks have changed to reflect task 74 starting earlier.
  • Hit cancel in the task editor. Now the weird stuff begins...
  • :!: (Still happens) First, after hitting cancel, you'll notice that while the milestone has reverted correctly to its previous state, the subtasks have have not.
  • :!: (Still happens) Notice also that the effort for tasks in rows 78 to 81 have changed. That should never happen.

Could all this be due to inconsistencies in the data?

I suggest to wait till the issue gets resolved and then re-check how it looks.
The test case is rather big so potentially there could be some other issues but it's better to shoot them one by one.
