[jira] Commented: (JCR-1053) Calling size method of a
ManageableArrayList causes NullPointerException
[ https://issues.apache.org/jira/browse/JCR-1053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12520387 ]
Christophe Lombart commented on JCR-1053:
-----------------------------------------
Testing on !parentNode.hasNodes() is not sufficient. We have to check if the parent node has children based on a specific type. The type use for the collection elements. It is possible to have other children (based on another nt) which are not element of the collection.

> Key: JCR-1053
> URL: https://issues.apache.org/jira/browse/JCR-1053
> Project: Jackrabbit
> Issue Type: Bug
> Components: jcr-mapping
> Affects Versions: 1.3
> Reporter: André Bierwolf
> Assignee: Christophe Lombart
> Attachments: NTCollectionConverterImpl.diff
>
>
> When using the NTCollectionConverterImpl with proxy="true" a call on the size () method of a ManageableArrayList causes a NullPointerException if there is no underlying List. LazyCollectionLoader doLoad returns null because there is are no children.
> The ManageableArrayList is created because the isNull method of the NTCollectionConverterImpl class always returns false.
> According to the comment line this is done because the getCollectionNodes always returns a list.
> But after the fix for JCR-882 this is not correct anymore.
> The attached fix corrects this.
> The only question remaining is how to differ between an empty list and a null-value for the field containing the list.
