Issue/Introduction

Error Message :
Access violation in module C:\AutomationEngine\bin\ZUSYNCHK.dll at 00007FFDBF47955C on read FFFFFFFFFFFFFFFF

When a task containing a PromptSet which uses a VARA.EXE as a data source is executed, the task remains in a 'Waiting for user input' status and the prompt set dialog box never appears.

Investigation

A task (job or workflow) has a PromptSet whose default values are specified at the workflow level.
The default values contain curly-brace-style VARA object references such as "{VARA,KEY, COLUMN}" that references a VARA.EXEC, which is a different VARA than the data source.

The referenced VARA.EXEC objects work fine on their own and clicking the 'Preview' button returns the expected results:

If the task is executed via the Java User Interface, it will hang completely and must be killed.
If it is executed in the AWI, the connection will be lost.
