[jira] [Updated] (SLING-9417) Content-type and InputStream are null
when accessing nt:file resources with ";v="
[ https://issues.apache.org/jira/browse/SLING-9417?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Matthias Herold updated SLING-9417:
-----------------------------------
Description:
When using the methods resource.getMetadata().getContentType() or resource.adaptTo(InputStream.class), both methods return null when:
# the resource is a child of a versionable node,
# the resource is of type nt:file, and
# resource has been looked up with a version identifier in the URL (";v=").
From my understanding, both methods should return the relevant values from the frozen node. The error occurs because of line 185 in JcrNodeResource.java
{\{ Node content = node.isNodeType(NT_FILE)}}
\{{ ? node.getNode(JCR_CONTENT)}}
\{{ : node.isNodeType(NT_LINKEDFILE) ? node.getProperty(JCR_CONTENT).getNode() : node;}}
When the resource is looked up with the version modifier, the ode type will not nt:file. Instead it is jcr:frozenNode with a property jcr:frozenPrimaryType set to nt:file. Therefore, the above code fails and will not use the jcr:content subnode, but the node itself. In my opinion, it would be right to change this to:
{{Node content = (node.isNodeType(NodeType.NT_FILE) || (node.isNodeType("nt:frozenNode") && node.hasProperty("jcr:frozenPrimaryType") }}
\{{ && node.getProperty("jcr:frozenPrimaryType").getString().equals(NT_FILE)))}}
\{{ ? node.getNode(Node.JCR_CONTENT)}}
\{{ : node.isNodeType(JcrConstants.NT_LINKEDFILE) ? node.getProperty(Node.JCR_CONTENT).getNode() : node;}}
JcrResourceMetadata has the same issue (line 65):
{\{ if ( (!nodePromotionChecked) && node.isNodeType(NT_FILE)) {}}
This could be changed to:
{\{ if ( (!nodePromotionChecked) && (node.isNodeType(NT_FILE) ||}}
\{{ (node.isNodeType("nt:frozenNode") && node.hasProperty("jcr:frozenPrimaryType") }}
\{{ && node.getProperty("jcr:frozenPrimaryType").getString().equals(NT_FILE)))) {}}
As I'm still a newbie in Sling, I'm not sure if the proposed solution is completely right. At the moment, I use a ResourceDecorator for my project with these changes and this fixes my problem - but there might be a better way to solve this.
