I am using jbpm 5.2 to develope my web application.
I am using ad hoc process for the application.
I want to set and get the process variable for the process.
I am not getting any way for that. Please help for that.
the null that you are sending as a parameter is the Event it self that can contain information and be mapped to a process variable.
Can you give us more context about what do you want to achieve?
