this primefaceExemple을 사용하여 treeTable을 만들고 싶습니다.Primefaces, 자식 노드 무한 포함

동적으로 설정하기 위해 객체로 반복 중입니다.

나는 때문에, 이해가 안 돼요 첫 번째 모듈 만 모듈 버전을 얻습니다. 다른 두 모듈은 아닙니다!

오른쪽에있는 룹트를 클릭 할 때 moduleVersion 루프 클릭 할 때

또한, 모듈 정보는 모듈 버전 정보 대신 writen됩니다 Snite

감사합니다,

처음 두 개의 중첩 된 for-loops로 인해 각 모듈에 모든 Module의 ModuleVersions을 추가하고 있습니다. 나는 내부 for-loop (for(ModuleVersion mv:)를 원래 for-loop로 옮겼다 :

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; 
}

감사합니다. 이전에 당신과 같은 루프를 만들려고했지만 부모 노드가 자식 노드를 추가하기 전에 종료되지 않았다는 예외가있었습니다. 코드는 괜찮습니다. 감사합니다! – Snite
