Hallo,<br>
<br>
I have a rule like this, defined in Guvnor:<br>
when<br>
Activity ( $date : date, workingTime > 240)<br>
<br>
then<br>
System.out.println("Working time limit has been reached");<br>
violatedRegulation.add(new String("regulation.general.working1"));<br>
<br>
<br>
violatedRegulation is a List<String> which I set as a global because later<br>
on I will extract the content of that list which is a key defined in a<br>
properties file<br>
<br>
ksession.setGlobal("violatedRegulation", violatedRegulation);<br>
ksession.executeObject(activity);<br>
<br>
<br>
but then I got the following exception:<br>
15:52:59,687 INFO [STDOUT] Working time limit has been reached<br>
15:52:59,687 ERROR [MyExceptionInterceptor] [Error: could not create<br>
