How to keep the assigned entity to a workflow when navigating between several forms (cubeview)

Example:

On the workflow France I have the choice between 3 entities

I choose to input the package of the entity FR0200. I select a first time the entity FR0200 (1)

When I go on a second form, I lose the entity and fall back on the first entity FR0220 (2)

The entity viewpoint is set from a parameter as below:

Parameter type : Bound List

Result format string type : Default

Method type : WorkflowProfileAndDescendantEntities

thank you for your return
