Script QPAC has an issue, in fact when the script is encoded and placed into the database, it seemed to mess up the CDATA brackets.
Therefore if you close workflow designer and then open it again trying to load the process map, the Script QPAC wouldn't open and give an error message, does any body have a workaround for this issue ?
I have LC WF 7.01 installed using the Script QPAC from SDK 7.03.
I created a simple 1 step process consisting of a Script QPAC with the following code:
System.out.println("&&&&&&&& HELLO &&&&&&&&");
When I test the workflow, I am presented with &&&&&&&& HELLO &&&&&&&& in the command window.
This, and the fact that you tried unsuccessfully to use the newer version of the QPAC, indicates to me that you should upgrade to the current shipping version of Adobe LiveCycle Workflow.
