4.3.2 Struct Properties

Struct properties are special because they might prevent the Content Server from restart. This is because struct properties might contain link or link list properties with links which are restricted to specific content types (see Example 4.6, “ Struct XML with link list property ”).

<?xml version="1.0" encoding="UTF-8"?>
<Struct xmlns="http://www.coremedia.com/2008/struct"
        xmlns:xlink="http://www.w3.org/1999/xlink">

  <StringProperty Name="string">foo</StringProperty>
  <LinkProperty Name="link"
                LinkType="coremedia:///cap/contenttype/CMArticle"
                xlink:href="coremedia:///cap/content/2"/>
  <StructProperty Name="substruct">
    <Struct>
      <LinkListProperty Name="links"
                        LinkType="coremedia:///cap/contenttype/Content_">
        <Link xlink:href="coremedia:///cap/content/2"/>
        <Link xlink:href="coremedia:///cap/content/102"/>
      </LinkListProperty>
    </Struct>
  </StructProperty>
</Struct>

Example 4.6. Struct XML with link list property

If you change the content type name, these links are invalid and you get an error.

java.lang.NullPointerException
at
com.coremedia.cotopaxi.struct.xml.StructUnHandler.unparseLinkList(StructUnHandler.java:194)
