    big tree loading slow when switchType is client

    jieshengz Newbie

      My setup is
      Richfaces 3.1.4 GA, Firefox,local deployment. My tree has 1000 nodes in 3 levels 10x10x10. It takes about 1 to 3 minutes to load if switchType is client. It seems ok if switchType is ajax. However, I'd like to use client switchType to reduce client-server traffic.

      Here is my xhtml code.

      The Java Code for root bean
      
      
      
      public class Root {
      
       public Node[] getRoots() {
      
       Node node = new Node(0, "0");
      
       Node[] nodes = node.getNodes();
      
       return nodes;
       }
      
      
      }
      
      


      The Java code for Node bean
      
      public class Node {
      
       protected int level;
       protected String label;
       public Node(int level, String label)
       {
       this.level=level;
       this.label=label;
       }
      
       public String getLabel()
       {
       return label;
       }
      
      
      
       public Node[] getNodes()
       {
       if (level<3)
       {
       Node[] nodes= new Node[10];
       for (int i=0; i<10; i++)
       {
       nodes=new Node(level+1, String.valueOf(i));
       }
       return nodes;
       }else
       {
       //no child
       return new Node[0];
       }
      
       }
      
       public String toString()
       {
       return level+"."+label;
       }
      
       public int getLevel() {
       return level;
       }
      
       public void setLevel(int level) {
       this.level = level;
       }
       }
      
      


      Any suggestion or workaround?

      Thanks
