Example: Persistent content within workflows

Within workflows, content can also be saved via the session and read out again after switching a transition.

Within the “DoSelectCounting” activity, a counter can be incremented by a value of 1 each time a workflow is run. The value of the counter is saved and incremented by 1 as soon as the workflow is started again. The value is shown to the user within an information dialog.

For information on pop-up dialogs, see Workflows / Messages and Plug-In Development / Message Boxes.
