[TUSCANY-4078] Inheritance problem when subtypes are in different namespaces

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: Java-SDO-1.1
• Component/s: Java SDO Tools
• Labels: patch
• Environment: Java 6, eclipse indigo, RHEL 6.3
• Assignee: Unassigned

Description

NullPointerException is thrown during generating SDO Java classes from XSD when there is a specific situation in a XSD model that is there is more than one inheritance level for instance type TC extends TB and TB extends TA and additionally each of the classes (complexTypees) is in different package (namespace), for instance
pa.TA, pb.TB, pc.TC (p is for package, T is for Type, and V is for ...)

This might be a EMF bug (version 2.2.3).
