RF4: rich:tree does not work

[vrelits]

Hi!

I've more or less copied the tree example from the showcase:

<rich:tree toggleType="ajax" var="item" >

                <rich:treeModelRecursiveAdaptor roots="#{controller.fileSystemNode}"  nodes="#{item.directories}">

                    <rich:treeNode>

                        #{item.shortPath}

                    </rich:treeNode>

                    <rich:treeModelAdaptor nodes="#{item.files}">

                        <rich:treeNode>#{item}</rich:treeNode>

                    </rich:treeModelAdaptor>

                </rich:treeModelRecursiveAdaptor>

            </rich:tree>

BUT it does not seem to work.

I can see that controller.fileSystemNode get called alright and returns FileSystemNode which has getDirectories and getFiles (much like showcase examples).

The problem however seems that nodes="#{item.directories}" resolves to NULL and therefore nothing is displayed.

getDirectories of FileSystemNode is never called.

Is this supposed to work. How is FileSystemNode put into "item" so that #{item.directories} will resolve?

you should pass not just filesystemnode object but actuall roots collection.. look to sources from 3.3.x (almost the same for the 4 used)

package org.richfaces.treemodeladaptor;

public class FileSystemBean {

    private static String SRC_PATH = "/WEB-INF/src";

    private FileSystemNode[] srcRoots;

    public synchronized FileSystemNode[] getSourceRoots() {

        if (srcRoots == null) {

            srcRoots = new FileSystemNode(SRC_PATH).getNodes();

        }

        return srcRoots;

    }

}

and

                <rich:treeModelRecursiveAdaptor roots="#{FSN.roots}"  nodes="#{item.directories}">

Hi Ilya!

Thanks. That was the cause. Not sure how I could miss that small detail.

Hi,

I am newby in JAVA and richfaces and I have the same problem, because in the class (in example) there is no method "getNodes".

Could You send me code example or explain how it make work ?

Thanks a lot !
