Nested views do not properly round-trip through REST or CLI due to missing View.owner

XMLWordPrintable

      If you retrieve a NestedView from either REST (GET /view/.../config.xml) or CLI (get-view), and then save it right back (POST /view/.../config.xml, update-view or create-view after deleting), the resulting view does not render. Depending on the subview you get either

      java.lang.NullPointerException
    hudson.model.View._getOwnerItemGroup(View.java:269)
    hudson.model.View.getOwnerItemGroup(View.java:258)
    hudson.model.ListView.getItems(ListView.java:168)
    hudson.model.ListView.getItems(ListView.java:66)
    hudson.model.View.filterQueue(View.java:462)
    hudson.model.View.getApproximateQueueItemsQuickly(View.java:483)

      or

      java.lang.NullPointerException: Cannot invoke method isEmpty() on null object
    org.codehaus.groovy.runtime.NullObject.invokeMethod(NullObject.java:77)
    org.codehaus.groovy.runtime.callsite.PogoMetaClassSite.call(PogoMetaClassSite.java:45)
    org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:42)
    org.codehaus.groovy.runtime.callsite.NullCallSite.call(NullCallSite.java:32)
    org.codehaus.groovy.runtime.callsite.CallSiteArray.defaultCall(CallSiteArray.java:42)
    java_util_List$isEmpty.call(Unknown Source)
    hudson.model.View.main.run(main.groovy:6)

      (both stack traces from 1.554.x).

      The reason is that View.writeXml explicitly omits the View.owner field when writing, yet NestedView.views makes no attempt to restore it when loading XML.

      The workaround is to add

      <owner class="hudson.plugins.nested_view.NestedView" reference="../../.."/>

      inside every nested view (<hudson.model.ListView> etc.) before sending the XML back to Jenkins.
