Hi,
The sequential execution mode throws an exception when working with
the new API. It works fine with the old API.
I used the following configuration:
KnowledgeBaseConfiguration configuration =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
configuration.setOption(SequentialOption.YES);
Thanks for finding this, It's now fixed in trunk.
This exception has been thrown:
java.lang.ArrayIndexOutOfBoundsException: -1

For this rule:
rule "Hello World"
when
Message()
then
System.out.println( "test" );
end
Tested with snapshot from 7. Mar 2009
Best Regards,
Michal
