SessionSubmit @ Print @ $SynchronousEvaluation
False even though ref/SessionSubmit/Details last point:
The task is run preemptively, both when the system is waiting for input and during other evaluations.
And ref/$SynchronousEvaluation/Details 3rd point:
synchronous evaluation is the same as a preemptive evaluation.
- I expected
True. Is this a bug or is it a documentation inconsistency (see below).
Following notes are only loosely connected to the main question so one does not need to read further.
Next point in $SynchronousEvaluation says:
Synchronous evaluations halt the system while being evaluated.
This is not true for scheduled tasks, you can move the slider during the pause:
Slider SessionSubmit @ Pause
While you can't move it during this pause:
Slider Dynamic @ Pause
I guess the bottom line is that there is a difference between a preemptive evaluation in general and a preemptive evaluation coming from the preemptive link. And that difference needs more documentation space.
