Modeshape: Not able to add child node

nimit.agrawal Apr 9, 2014 11:22 AM

I am not able to add a child node.

I have defined 2 templates parent and a child.

I can successfully add a parent node. when i am trying to add child node i am getting error.

javax.jcr.nodetype.ConstraintViolationException: Unable to determine a valid node definition for the node "/parent/FirstParent/FirstChild" in workspace "default" of "testRepo"



public class TestCase {


    @Inject
    private Repository repository;




    public void main(String[] args) throws LoginException, Exception {
        Session session = repository.login();


        session.getWorkspace().getNamespaceRegistry().registerNamespace("ns", "www.com");


        NodeTypeManager nodeTypeManager = session.getWorkspace().getNodeTypeManager();


        NodeTypeTemplate template1 = nodeTypeManager.createNodeTypeTemplate();
        template1.setName("ns:parent");
        template1.setOrderableChildNodes(false);
        template1.setQueryable(false);


        // Adding property definition
        PropertyDefinitionTemplate prop = nodeTypeManager.createPropertyDefinitionTemplate();
        prop.setName("host");
        prop.setRequiredType(PropertyType.STRING);
        prop.setMandatory(false);
        prop.setDefaultValues(new Value[] { session.getValueFactory().createValue("localhost") });
        template1.getPropertyDefinitionTemplates().add(prop);


        // Adding child node definition
        NodeDefinitionTemplate childTemplate = nodeTypeManager.createNodeDefinitionTemplate();
        childTemplate.setName("ns:child");
        childTemplate.setDefaultPrimaryTypeName("ns:parent");
        childTemplate.setMandatory(false);
        childTemplate.setProtected(false);
        template1.getNodeDefinitionTemplates().add(childTemplate);


        nodeTypeManager.registerNodeType(template1, true);


        NodeTypeTemplate template2 = nodeTypeManager.createNodeTypeTemplate();
        template2.setName("ns:child");
        template2.setOrderableChildNodes(false);
        template2.setQueryable(false);
        
        PropertyDefinitionTemplate prop2 = nodeTypeManager.createPropertyDefinitionTemplate();
        prop2.setName("host");
        prop2.setRequiredType(PropertyType.STRING);
        prop2.setMandatory(false);
        prop2.setDefaultValues(new Value[] { session.getValueFactory().createValue("localhost") });
        template2.getPropertyDefinitionTemplates().add(prop2);


        nodeTypeManager.registerNodeType(template2, true);


        Node rootNode = session.getRootNode().getNode("ns");


        Node firstParentNode = rootNode.addNode("FirstParent", "ns:parent");


        // Getting error in this line
        firstParentNode.addNode("FirstChild", "ns:child");


    }
}

Thanks in advance

        // Adding child node definition
        NodeDefinitionTemplate childTemplate = nodeTypeManager.createNodeDefinitionTemplate();
        childTemplate.setName("ns:child");
        childTemplate.setDefaultPrimaryTypeName("ns:parent");
        childTemplate.setMandatory(false);
        childTemplate.setProtected(false);
        template1.getNodeDefinitionTemplates().add(childTemplate);

        // Getting error in this line
        firstParentNode.addNode("FirstChild", "ns:child");
}

Your child definition has the name: [ns:child] and the type [ns:parent]. This means that if you want such a child to "firstParentNode" your code should look like: firstParentNode.addNode("ns:child", "ns:parent") (you need to make the distinction between a NodeTypeTemplate and a NodeDefinitionTemplate)

If you want to be able to use any name for the child node and have the [ns:child] primary type, your code should look like this:

childTemplate.setName("*"); childTemplate.setDefaultPrimaryTypeName("ns:child");
