Subject [jira] Resolved: (JCR-2501) Repository descriptor returns null for QUERY_LANGUAGES
Date Thu, 18 Feb 2010 11:15:30 GMT

     [ https://issues.apache.org/jira/browse/JCR-2501?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Stefan Guggisberg resolved JCR-2501.
------------------------------------

    Resolution: Invalid

the Repository.QUERY_LANGUAGES descriptor value is defined as an array of strings.

the descriptor should therefore be queried with the following method: 

    Value[] Repository#getDescriptorValues(String key);

Repository.getDescriptor and Repository.getDescriptorValue OTOH  always return null for multi-value
descriptors.

for more information, please see the jcr 2.0 spec:

- 24.2 Reposiotory Descriptors
- 24.2.5 Query

> Using the repository descriptor table to check support for query languages, I get a null.
 Here's the code.
>  session.getRepository().getDescriptor(Repository.QUERY_LANGUAGES )
> BUT, if I use the queryManager's getter, seen below, I see that the repo does indeed
support the 4 languages, as it should.   
>    queryManager.getSupportedQueryLanguages();
> Seems like a simple bug.
