Each step in an activity could have a designated step page. This is not a special page or a page with specific characteristics, but a reference to a clipboard page that is available to the activity (or a to new page that is created by the step).
The step page becomes the primary page for the duration of this step's execution. Usually, the method in that step accesses or updates properties on that page.
Within a Java step or function rule body, the keyword myStepPage
refers to the step page.
