I get the following error when trying to set a variable for a taskInstance.

This is the method I'm using to save the task.

|
| public void save(Hashtable taskVariables, String transition)
| {
|
| TaskInstance taskInstance = taskMgmtSession.loadTaskInstance
(taskInstanceId);
|
| if(taskVariables != null && taskVariables.size() > 0)
| {
| Iterator i = taskVariables.keySet().iterator();
| while(i.hasNext()){
| String key = (String)i.next();
| Object value = taskVariables.get(key);
| taskInstance.setVariable(key, value);
| }
| }
| taskInstance.end(transition);
|
| jbpmContext.save(taskInstance);
|
|
| }
|

I'm using also the filters that come with the starters-kit.
