Unable to properly restore a previous version of a node that contains
multivalue properties.
--------------------------------------------------------------------------------------------
Key: JCR-908
URL: https://issues.apache.org/jira/browse/JCR-908
Project: Jackrabbit
Issue Type: Bug
Components: core
Affects Versions: 1.3
Reporter: Bob Wieler
An ArrayIndexOutOfBoundsException occurs when I am trying to restore a previous
version of a node when it contains empty multi value properties.
Here is a stack trace for where in he core code the exception is occurring:
Exception in thread "AWT-EventQueue-0"
java.lang.ArrayIndexOutOfBoundsException: 0
at
org.apache.jackrabbit.core.NodeImpl.restoreFrozenState(NodeImpl.java:3856)
at
org.apache.jackrabbit.core.NodeImpl.internalRestore(NodeImpl.java:3799)
at
org.apache.jackrabbit.core.NodeImpl.internalRestore(NodeImpl.java:3760)
at org.apache.jackrabbit.core.NodeImpl.restore(NodeImpl.java:3057)
...
Line 3856 in NodeImpl.restoreFrozenState is:
internalSetProperty(props[i].getName(), prop.getValues()[0]);
This is always being called even for multivalued properties (the previous "if
(prop.isMultiValued())" is always returning false). Even if I have a value in
the multi-value property, only the first item is restored because the
prop.isMultiValued() call in NodeImpl.restoreFrozenState() never returns true
regardless of whether the property is multivalued or not.
The node definition is:
<nodeType name="bob:customType"
isMixin="false"
hasOrderableChildNodes="false"
primaryItemName="">
<supertypes>
<supertype>mix:lockable</supertype>
<supertype>mix:versionable</supertype>
</supertypes>
<propertyDefinition name="bob:properties"
requiredType="Reference"
autoCreated="false"
mandatory="true"
onParentVersion="COPY"
protected="false"
multiple="true"/>
</nodeType>
A new node is created with the primary type being "bob:customType" and an empty
array of References is set as the value for that property in the node.
