Please provide exact steps to reproduce the issue.
Comment 3 dcherk 2009-11-17 10:32:07 UTC 
here's the structure that resulted in the NPE for me:

  <xs:element name="userOrderBy">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="field" minOccurs="1" maxOccurs="1">
          <xs:complexType>
            <xs:restriction base="xs:string">
              <xs:enumeration value="userId"/>
              <xs:enumeration value="name"/>
              <xs:enumeration value="email"/>
              <xs:enumeration value="employeeNumber"/>
              <xs:enumeration value="departureDate"/>
              <xs:enumeration value="lastLoginDateTime"/>
              <xs:enumeration value="supervisorUserId"/>
              <xs:enumeration value="supervisorName"/>
              <xs:enumeration value="supervisorEmail"/>
              <xs:enumeration value="supervisorEmployeeNumber"/>
            </xs:restriction>
            <xs:attribute ref="rram:sortDirection" />
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>

Its obviously incorrect, and validation errors should have happened.

Would you please attach the whole schema.

Report from old NetBeans version. Due to code changes since it was reported likely not reproducible now. Feel free to reopen if happens in 8.0.2 or 8.1.
