Re: [rules-users] Is Drools 5.1 backward compatible with 5.0.1?
Are the test cases failed because of
java.lang.NullPointerException

I checked the source of CommandFactoryProviderImpl (5.1.0.CR1) and found this
public Command newInsertElements(Iterable objects) {
// TODO: FIX THIS
// return new InsertElementsCommand(objects);
return null;
}
But it has been fixed in 5.1 FINAL.

Hi,
I am new to Drools and learning it by reading "Drools JBoss Rules 5.0
Developer's Guide" at the moment.
However, the test cases of chapter 3 was failed when execute with Drools
5.1.0.CR1.
I suspect the test is broken due to the sequential option enabled with code
block below:
KnowledgeBaseConfiguration configuration =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
configuration.setOption(SequentialOption.YES);
You can view the complete code at
http://code.google.com/p/droolsbook/source/browse/trunk/droolsBookParent/...
Is this code block compatible with Drools 5.1? As it is working without any
problem in 5.0.1.
If it is incompatible, I would like to know how to migrate it to Drools
5.1.0.
Please advice.
Thanks,
Chee Kin
