Could it be that the fact where the NPE happens during its insert contains a field of some wrapper type (e.g.)Integer that's null and needs to be converted to a simple type (e.g. int)? <br><br>But the same NPE should happen when you insert the same fact with rules coming from a single file - but you'll know whether you have changed the facts.<br>

Mmmh,<br>
<br>
i still get an NPE but from a different function within<br>
ClassFieldReader.java<br>
<br>
with the 4.07 Api calls it was<br>
<br>
at org.drools.base.ClassFieldReader.isNullValue(ClassFieldReader.java:183)<br>
<br>
now its<br>
<br>
java.lang.NullPointerException<br>
at org.drools.base.ClassFieldReader.getIndex(ClassFieldReader.java:78)<br>
at<br>
org.drools.util.LeftTupleIndexHashTable.<init>(LeftTupleIndexHashTable.java:48)<br>
at<br>
org.drools.util.LeftTupleIndexHashTable.<init>(LeftTupleIndexHashTable.java:35)<br>
at<br>
org.drools.common.DoubleBetaConstraints.createBetaMemory(DoubleBetaConstraints.java:231)<br>
at org.drools.reteoo.BetaNode.createMemory(BetaNode.java:340)<br>
.....<br>
<br>
i have no idea how to solve this at the moment.<br>
