Please provide exact steps to reproduce the issue

1) Create a very simple yet buggy XML schema:
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://xml.netbeans.org/schema/test"
    xmlns:tns="http://xml.netbeans.org/schema/test"
    elementFormDefault="qualified">
    <xsd:simpleType name="test"/>
</xsd:schema>
2) Switch to "Schema" view and select Simple Type named "test"
3) Right click, "Properties"
4) Click on "Structure... Customize"
5) In the Base Type part, select an existing definition, let's say "string"
An NPE appears.

I guess the reason is because no Derivation Method is selected, because as soon as you select a "Restriction", you can
select the Base type from existing definition.
