In my evaluation of Activiti over the past 2 weeks, all I can say is that I saw that Stack Trace numerous times - and I had trouble figure the root cause in the code. That being said, when I clicked on more buttons on the process steps, like "Part of Process" or attempting to view the active process for a particular user, I typically found stack traces that were more meaningful to me. It just seems that this stack trace is usually in combination of something else bad that is happening. (Which ultimately leads to this trace which involves firing off Events on null data.)
Maybe a core developer will have better advice
Mine is to just keep clicking and hope for a better stack trace.
There are also a number of people that have reported an exception trace on:
at org.activiti.explorer.ui.form.FormPropertiesForm.access$000(FormPropertiesForm.java:45)
at org.activiti.explorer.ui.form.FormPropertiesForm$1.buttonClick(FormPropertiesForm.java:139)
on the forums here, and even some with advice on what to fix. Take a look.
FormPropertiesForm.java shows:
..
45 public class FormPropertiesForm extends VerticalLayout {
..
..
..
138 Map<String, String> formProperties = formPropertiesComponent.getFormPropertyValues();
139 fireEvent(new FormPropertiesEvent(FormPropertiesForm.this, FormPropertiesEvent.TYPE_SUBMIT, formProperties));
..
From here, it seems that a null event is sent into vaadin and it chokes.
