duration of a task during holidays

Good morning all,

I don’t understand vacation management.
I do a test with two spots
• Task A – 10 days - beginning of the task on March 7 – resources Jean
• Task B – 10 days - beginning of the task on March 7 – resources Michel
• Jean is on leave from March 9 to March 16

In the Gantt chart ends both spots end on March 18th.
Normally task A should finish March 25th.

Is it normal or not?

GanttProject ignores resource vacations when making a schedule, sorry.

thank you for the answer

is this an option that will be added in the next version?

It is quite a complicated feature that requires non-trivial changes and a lot of time. Chances of making it in the literally next version are next to zero, sorry.

Ok I understand that it is not easy.
