Did you rather mean "I shouldn't use automatic activity" ?
I tried already to use custom element but I didn't succeed to make it go to the next step. I used this code :
Execution execution = processInstance.findActiveExecutionIn("wait");
executionService.signalExecutionById(execution.getId());
but when I execute that, i have NullpointerException, it is the execution object that is null. Do you have an idea about what makes the problem?
As you described it here, I can't execute an swing Frame to make process continue. Is that true??
