now I want to mention 'id' value in the 'assignee' property of the newly created task .. will you please help me to achieve this(on how to capture id and mention it in the next task assignee field ) ? thanks in advance.
Not sure why you're using REST for this … in your model, you need to set the assignee with an expression that does the same logic (but probably in Java) like assignee="${myCustomBean.getAssigneeFromPreviousTask()}"
