Hey,
i have a simple ruleflow with some split and ruleflowgroup components.
Now i want some user interaction while the ruleflow is runing.
For example : a ruleflowgroup is executed, than check a global or what ever
and
fire an event, so i can interact with the user. After the answer modify
a g
Now i found my fault !
What i did wrong was writting every single drl -file into seperate pkg -
file
instead of writing them in one single pkg - file.
I find my error in reasoning with the follow code (modified hello world
example from drools
project wizzard). Adding the two drl - files result
now i found out, that my problems are in relation to my serialized
KnowledgePackages.
When i use the following code and load the drl files everything is fine !
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource(rules[i] +

The rules and the facts are the same.
So i add the source to the project and (try to) debug into the code.

in
the "setReadAccessor" method, but the meth
Mmmh,
i still get an NPE but from a different function within
ClassFieldReader.java
with the 4.07 Api calls it was
at org.drools.base.ClassFieldReader.isNullValue(ClassFieldReader.java:183)
now its
java.lang.NullPointerException
at org.drools.base.ClassFieldReader.getIndex(ClassFiel
Thanks so far - i will change the api calls and post my results.
