Alexander Klimetschek commented on JCR-325:
-------------------------------------------
As this is compliant with the spec and implementation is not trivial, this bug
hasn't been solved yet. Generally there is no garantee that you can map a JCR
structure to an XML document view - especially when you use a JCR-only feature
such as multi-value properties. See also the comment above:
> changing type to 'Improvement' as current implementation (skipping
> mutli-valued properties on document view export) is compliant with "6.4.2.5
> Multi-value Properties" of the spec.
> docview roundtripping does not work with multivalue non-string properties

> Key: JCR-325
> URL: https://issues.apache.org/jira/browse/JCR-325
> Project: Jackrabbit
> Issue Type: Improvement
> Components: xml
> Affects Versions: 0.9, 1.0
> Environment: jackrabbit r379292
> Reporter: Tobias Bocanegra
> Assignee: Jukka Zitting
> Attachments: namespace-context.patch, xml-refactoring.patch
>
>
> when exporting a multivalue property with docview, the property values are
> serialized to a space delimited list in the xml attributes:
> for example:
> <?xml version="1.0" encoding="UTF-8"?>
> .
> .
> <testNode
> jcr:primaryType="refTest"
> refs="b5c12524-5446-4c1a-b024-77f623680271
> 7b4d4e6f-9515-47d8-a77c-b4beeaf469bc"
> />
> the refTest nodetype was:
> [refTest]
> - refs (reference) multiple
> importing this docview fails with: javax.jcr.ValueFormatException: not a
> valid UUID format
> this is due to the fact, that the space delimited list is not exploded
> anymore. actually this code is commented:
> org.apache.jackrabbit.core.xml.DocViewImportHandler, lines 191 - 200:
> /*
> // @todo should attribute value be interpreted as LIST type
> (i.e. multi-valued property)?
> String[] strings = Text.explode(attrValue, ' ', true);
> propValues = new Value[strings.length];
> for (int j = 0; j < strings.length; j++) {
> // decode encoded blanks in value
> strings[j] = Text.replace(strings[j], "_x0020_", " ");
> propValues[j] = InternalValue.create(strings[j]);
> }
> */
> i haven't tested, but i assume this also fails for all other non-string
> property types.
