I have two nodes in a cluster. "Node 1" uses workspace1 and "Node 2" uses workspace2. The new type "searchable" is registered on "Node 1". When I try to create a new node of type "searchable" on "Node 2" then the the source code bellow writes twice null to STD.

NEW NODE TYPE:
NodeTypeTemplate nodeType = nodeTypeManager.createNodeTypeTemplate();
nodeType.setName("searchable");
nodeType.setMixin(true);

PropertyDefinitionTemplate property = nodeTypeManager.createPropertyDefinitionTemplate();
property.setName("keywords");
property.setMultiple(true);
property.setRequiredType(PropertyType.STRING);
nodeType.getPropertyDefinitionTemplates().add(property);
// Register the custom node type
nodeTypeManager.registerNodeType(nodeType,false);

SOURCE:
Session session = client.getSession();
Node root = session.getRootNode();
Node folder = root.addNode("searchableFolder", "nt:folder");
folder.addMixin("searchable");
Property property = folder.setProperty("keywords", "k1");
System.out.println("Property definition:" + property.getDefinition());
session.save();
System.out.println("Property definition:" + property.getDefinition());
