Remove variable from a process instance

[milhaim]

Hi All,

to add a varaibale to a process instance I'm using this code :

WorkflowProcessInstanceImpl processInstance = (WorkflowProcessInstanceImpl) ksession.getProcessInstance(processInstanceId);

processInstance.setVariable(variableName, variableValue);

My Question is how to remove this variable ?

Many thanks.

Have you tried to set the variable to null? as far as I know jbpm5 does not handle null variables so it will be considered as removed.

Hi Maciej,

Yes, this is what I am using actually. I was checking if there isn't another way to do it.

Thanks for your answer.
