Get process data of a delayed task

This is a known issue - or - it works as designed.

The method ITask.getStartProcessData() returns the 'in' object of the process-data.

On a Task Switch Element this in-object is created, when the Task is created. Therefore, as soon as the Task exists, also the start process data exists.

When a Request Start Element is triggered, the in-object will be created when the start element is executeded. Because the Request Start Element is triggered, this element is no executed on Task creation and therefore no start process data exists.

As a workaround you could run the triggered Task as System and in a next Step you create the Task for the user with a normal Task Switch.

If you are interessted on the param-object (this one is available on a triggered task), you could call the below method. Please note, this is NOT public API!

public final class MyHelper {
    private MyHelper(){}

    public static Tuple getTriggeredTaskStartParamTuple(final ITask task) throws Exception {
        return SecurityManagerFactory.getSecurityManager().executeAsSystem(
            new Callable<Tuple>() {
                @Override
                public Tuple call() throws Exception {
                    IProcessData processData = task.getInternalStartProcessData();
                    if (processData != null && ArrayUtils.contains(processData.getValueNames(), "param")) {
                        Object paramTuple = processData.getValue("param");
                        if (paramTuple instanceof Tuple) {
                            return (Tuple) paramTuple;
                        }
                    }
                    return null;
                }
            });
    }
}
