BUG FIX: Setting Counterbalancing in List does not generate proper E-Basic script [17334]

This article applies to:
E-Prime 1.1
E-Prime 1.0

This bug has been fixed in E-Prime 1.1 SP1.

Symptoms
When using counterbalancing in an experiment, more than one row/level or none at all are sampled during the experiment. The expected behavior when counterbalancing is for only one row to be run/sampled based on the offset of the "group by" value.


Detail
Caused by an internal design error, the List does not correctly ensure that the reset condition is Samples=1, the exit condition is Samples=1, and Reset Every Run is True/Checked when using counterbalancing. This makes it so that running a List multiple times will not sample properly.


Solution
Update to E-Prime 1.1 SP1 or later.

E-Prime 1.1 Service Pack 1 ensures that the reset condition is Samples=1, the exit condition is Samples=1, and Reset Every Run is True/Checked and updates the interface accordingly. Experiments with improper values that are loaded into E-Prime 1.1 SP1 will have these values automatically changed.

Workaround

This workaround is intended only for those who are unable to update to the version of E-Prime that contains the bug fix:

Update to E-Prime 1.1 SP1 or later. Ensure that the reset condition is Samples=1, the exit condition is Samples=1, and Reset Every Run is True/Checked.
