the initial problem is resolved. now i found a new problem: i created a minimal process with a start task with 2 variables, a and b. then, i first pressed save in the task form that was presented after creation of the process instance. then i pressed the end task task button and this jbpm console error message (not a stacktrace) appeared : anonymous wrote : | Error | Show detailsError taking transition: task node does not have leaving transition 'End Task' please build the suite and make a few processes, deploy and test them in the console.
