Primefaces, infinite include of children node

Question

I want to create a treeTable using this primefaceExemple.

I'm looping into object to set it dynamically. Here is my bean code :

public class ModuleMB extends GenericMB<Module,ModuleService, Long> {

    @Autowired
    ModuleRepository moduleRepository;

    private Document selectedDocument;

    public ModuleMB() {
        super(Module.class);
    }

    @Autowired
    @Override
    public void setService(ModuleService service) {
        this.service = service;
    }

    public TreeNode getRoot() {
        TreeNode root = new DefaultTreeNode("root", null);
        Iterable<Module> moduleList = moduleRepository.findAll();
        for (Module m : moduleList) {
            TreeNode modules = new DefaultTreeNode(new Document(m.getLabel(), Long.toString(m.getLastModified()), m.getClass().getName()), root);
        }
        for (TreeNode curModuleNode : root.getChildren()) {
            System.out.println("ROWKEY : " + curModuleNode.getRowKey());
            for (Module m : moduleList) {
                System.out.println("MODULE LABEL : " + m.getLabel());
                for (ModuleVersion mv : m.getVersions()) {
                        System.out.println("MV LABEL : " + mv.getLabel());
                        TreeNode moduleVersions = new DefaultTreeNode(new Document(mv.getLabel(), Long.toString(mv.getLastModified()), mv.getClass().getName()), curModuleNode);
                    }
                }
        }
        return root;
    }

    public Document getSelectedDocument() {
        return selectedDocument;
    }

    public void setSelectedDocument(Document selectedDocument) {
        this.selectedDocument = selectedDocument;
    }
}

The view result is as below :

  • First Module of the IDF market
    • V1 (correct)
    • V2 (correct)
  • Second market of the IDF market
    • V1 (wrong, second module dont have any children)
    • V2 (wrong, second module dont have any children)
  • Test A
    • V1 (wrong, Test A dont have any children)
    • V2 (wrong, Test A module dont have any children)

Here the console output (I don't put all, because lot of repetition) :

I don't understand why my module version are attached to each module, because only the first module get module version, not the two others !

Plus, when clicking on the loopt at the right, the Module information are writen instead of the module version information when clicking on a moduleVersion loop :

Thanks for reading,

Solution

You are adding all Module's ModuleVersions to each module due to the first two nested for-loops. I moved the inner most for-loop (for(ModuleVersion mv:) into the original for-loop:

public TreeNode getRoot() {
    TreeNode root = new DefaultTreeNode("root", null);
    Iterable<Module> moduleList = moduleRepository.findAll();
    for (Module m : moduleList) {
        TreeNode moduleNode = new DefaultTreeNode(new Document(m.getLabel(), Long.toString(m.getLastModified()), m.getClass().getName()), root);
        System.out.println("ROWKEY : " + moduleNode.getRowKey());
        System.out.println("MODULE LABEL : " + m.getLabel());
        for (ModuleVersion mv : m.getVersions()) {
            System.out.println("MV LABEL : " + mv.getLabel());
            TreeNode moduleVersions = new DefaultTreeNode(new Document(mv.getLabel(), Long.toString(mv.getLastModified()), mv.getClass().getName()), curModuleNode);
        }
    }
    return root;
}
