我使用JSF 2.0和PrimeFaces 3.0，可以使TreeTable工作。/index.xhtml @69,62 value="#{Document .name}":类'Document'没有可读属性'name'。"
代码如下:

ManagedBean:
@ManagedBean
@SessionScoped
public class DocumentsController implements Serializable {
private TreeNode root;
public DocumentsController() {
root = new DefaultTreeNode("root", null);
TreeNode documents = new DefaultTreeNode(new Document("Documents", "-", "Folder"), root);
TreeNode pictures = new DefaultTreeNode(new Document("Pictures", "-", "Folder"), root);
TreeNode music = new DefaultTreeNode(new Document("Music", "-", "Folder"), root);
TreeNode work = new DefaultTreeNode(new Document("Work", "-", "Folder"), documents);
TreeNode primefaces = new DefaultTreeNode(new Document("PrimeFaces", "-", "Folder"), documents);
//Documents
TreeNode expenses = new DefaultTreeNode("document", new Document("Expenses.doc", "30 KB", "Word Document"), work);
TreeNode resume = new DefaultTreeNode("document", new Document("Resume.doc", "10 KB", "Word Document"), work);
TreeNode refdoc = new DefaultTreeNode("document", new Document("RefDoc.pages", "40 KB", "Pages Document"), primefaces);
//Pictures
TreeNode barca = new DefaultTreeNode("picture", new Document("barcelona.jpg", "30 KB", "JPEG Image"), pictures);
TreeNode primelogo = new DefaultTreeNode("picture", new Document("logo.jpg", "45 KB", "JPEG Image"), pictures);
TreeNode optimus = new DefaultTreeNode("picture", new Document("optimusprime.png", "96 KB", "PNG Image"), pictures);
//Music
TreeNode turkish = new DefaultTreeNode(new Document("Turkish", "-", "Folder"), music);
TreeNode cemKaraca = new DefaultTreeNode(new Document("Cem Karaca", "-", "Folder"), turkish);
TreeNode erkinKoray = new DefaultTreeNode(new Document("Erkin Koray", "-", "Folder"), turkish);
TreeNode mogollar = new DefaultTreeNode(new Document("Mogollar", "-", "Folder"), turkish);
TreeNode nemalacak = new DefaultTreeNode("mp3", new Document("Nem Alacak Felek Benim", "1500 KB", "Audio File"), cemKaraca);
TreeNode resimdeki = new DefaultTreeNode("mp3", new Document("Resimdeki Gozyaslari", "2400 KB", "Audio File"), cemKaraca);
TreeNode copculer = new DefaultTreeNode("mp3", new Document("Copculer", "2351 KB", "Audio File"), erkinKoray);
TreeNode oylebirgecer = new DefaultTreeNode("mp3", new Document("Oyle bir Gecer", "1794 KB", "Audio File"), erkinKoray);
TreeNode toprakana = new DefaultTreeNode("mp3", new Document("Toprak Ana", "1536 KB", "Audio File"), mogollar);
TreeNode bisiyapmali = new DefaultTreeNode("mp3", new Document("Bisi Yapmali", "2730 KB", "Audio File"), mogollar);
}
/**

* @return
*/
public TreeNode getRoot() {
return root;
}
}
豆:
class Document {
private String name;
private String size;
private String type;
public Document(String name, String size, String type) {
this.name = name;
this.size = size;
this.type = type;
}
public Document() {}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSize() {
return size;
}
public void setSize(String size) {
this.size = size;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
}
任何想法?这与showcase的方式完全相同:http://www.primefaces.org/showcase-labs/ui/treeTable.jsf
解决方案在下面。唯一的变化是，将bean从受保护访问更改为public:
public class Document {
private String name;
private String size;
private String type;
public Document(String name, String size, String type) {
this.name = name;
this.size = size;
this.type = type;
}
public Document() {}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSize() {
return size;
}
public void setSize(String size) {
this.size = size;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
}
谢谢你们了!
