I am having trouble invoking some of the sample processes delivered with the application. For instance, the Dynamic Document Generation example and even the very simple looking Variable Logger example throw an endpoint invocation error when I try to run them from Workspace. Does anybody know what the cause of such an error would be? Also, are all example processes meant to be started from Workspace in general?
They're not all meant to be started from Workspace. The one thing you need if you want to start a process from workspace is a form to display. So if the process doesn't contain a variable that can contain a form like Form, xfaForm, DocumentForm and is set to be IN, then the process won't start properly in workspace since there is nothing to show.
