Problem adding participants to a workflow
Hello.
I am trying to start a workflow (serial or parallel), but when I am assigning the participants, I get an error, and the workflow doesn't start.
In the log I can see the following messages:
javax.servlet.ServletException: On requestURL ...

What can be the problem?
Thanks in advance!
Best regards.

This issue should have been fixed with HF1. I'm running into the same problem still. Maybe try one of these variations:
WorkflowVariables[“participants”][(int)WorkflowVariables.index]]
WorkflowVariables[“participants”][WorkflowVariables[“index”]]
WorkflowVariables[“participants”][(int)WorkflowVariables[“index”]]
None of them worked for me, but they might work for you. My issue is from the brackets around the index workflow variable expression, the expression itself works fine.

WorkflowVariables["participants"].get(WorkflowVariables["index"]) or variations thereof?[Error: unable to resolve method: [Ljava.lang.String;.get() [arglength=1]] [Near : {… WorkflowVariables["participant ….}]
Can you add your entire scripts in code format to have an example of what you're trying to execute?
Thanks
