PROBLEM SUMMARY

USERS AFFECTED:
WebSphere Process Server 6.0.1.x users.

PROBLEM DESCRIPTION:
NullPointerException occured when WPS
builds bo from some schema definitions

RECOMMENDATION:
None

The NullPointerException happen in following scenario:
There are two complex type definitions in xsd. One type extends
another one. Parent type has a attribute with type of child
type. In such scenario, child BO's model may miss some
attributes in Parent BO. So when processing an instance of child
BO, it may can not find these attributes and throw a
NullPointerException.
The exception is:
java.lang.NullPointerException
at org.eclipse.emf.ecore.util.BasicExtendedMetaData.
getAffiliation(BasicExtendedMetaData.java(Compiled Code))
at org.eclipse.emf.ecore.impl.BasicEObjectImpl.
