Controlling Versioning with Java

I create a node and then write something to it. If the versioning is enabled, that creates two version, once when node is created and another when something is written to that node.Here is how i created the nodeChildAssociationRef association = nodeService.createNode(parentNode, ContentMo

Is there a reason that you don't create the node, write its contents, and then apply the versioning aspect?

By the way, in your example where you say "enable versioning like this", you add the cm:titled aspect instead of the cm:versionable aspect. Is there a reason for that?

I'm interested in this solution, as well. The reason I can't create a node, write its contents, and then apply the versioning aspect is because in my content model (that I can't change), the versioning aspect is mandatory.

Create the content first, then call createNode with the cm:content property set to the content you've created.


ContentWriter writer = contentService.getWriter(null,
            ContentModel.PROP_CONTENT, true);
      writer.setMimetype(MimetypeMap.MIMETYPE_TEXT_PLAIN);
      writer.setEncoding("UTF-8");

      BufferedWriter out = new BufferedWriter(new OutputStreamWriter(writer
            .getContentOutputStream()));
                out.write("I am writing some text in node")
‍‍‍‍‍‍‍‍‍‍

Add the following property to your contentProps map


contentProps.put( ContentModel.PROP_CONTENT, writer.getContentData());
‍‍‍

Now call your createNode, and the initial version that is created by alfresco auto applying the versionable aspect will contain your content.


ChildAssociationRef association = nodeService.createNode(parentNode,
            ContentModel.ASSOC_CONTAINS, QName.createQName(
                  NamespaceService.CONTENT_MODEL_PREFIX, resourceName),
            ContentModel.TYPE_CONTENT, contentProps);
