Consider the following scenario:
An exception has been encountered. This may be caused by an extension.
However, if you dismiss the error message and try again to type inside an expression field in the Workflow designer, a completion list still does not display, and you do not receive an error message.
This issue occurs because of a change in the presentation layer of the completion list. In this case, Workflow projects cannot create and display the completion list correctly.
