    JSF 2.2 Rich:Tree & h:selectBooleanCheckbox, how to link both of them together?

    Jean-Philippe VILLEMIN Newbie

      I'm stuck with a conception problem. I try to parse a folder to get all this directory and files. I want then to select some files using a checkbox to associate to a key reference.(to retrieve them by this key after in the backingBean to set my objects and to populate my database) A key could have several files associated. I don't see how to do it. I'll be great if i could have some help on this.

      I don't understand how to retrieve the data from the view in a backing bean because of the complex structure

      I write this for the jsf view

       

      <rich:tree id="tree" toggleType="client" selectionType="ajax" var="item" rowKeyVar="rowKeyVar" treeNodeVar="treeNodeVar">
      
        <rich:treeModelRecursiveAdaptor roots="#{fileSystemBean.sourceRoots}" nodes="#{item.directories}" rowKeyVar="rowKeyVar1" treeNodeVar="treeNodeVar1" >
      
        <rich:treeNode>#{item.shortPath} > </rich:treeNode>
      
        <rich:treeModelAdaptor nodes="#{item.files}">
        <rich:treeNode>
        #{item} <h:selectBooleanCheckbox id="selectAll"/> 
        </rich:treeNode>
        </rich:treeModelAdaptor>
      
        </rich:treeModelRecursiveAdaptor>
      
       </rich:tree>

       

      I created this backing bean :

       

       

      public class FileSystemNode {
      
      private String path;
      private String shortPath;
      private List<String> files;
      private List<FileSystemNode> directories;
      
      
      
      private static final Function<String, FileSystemNode> FACTORY = new Function<String, FileSystemNode>() {
      
        public FileSystemNode apply(String from) {
        return new FileSystemNode(from.substring(0, from.length() - 1));
        };
      
      };
      
      private static final Function<String, String> TO_SHORT_PATH = new Function<String, String>() {
      
        public String apply(String from) {
      
        int idx = from.lastIndexOf('/');
      
        if (idx < 0) {
        return from;
        }
      
        return from.substring(idx + 1);
        };
      
      };

        if (idx != -1) {
      
        shortPath = path.substring(idx + 1);
      
        } else {
      
        shortPath = path;
      
        }

        Iterables.addAll(files, transform(filter(getResourcePaths(), not(containsPattern("/$"))), TO_SHORT_PATH));
        }
      
        return files;
      }
      
      private Iterable<String> getResourcePaths() {
