adviseNodeOpened attribute not available in RichFaces 4.x?

[rbid]

I am trying to use this adviseNodeOpened attribute and Backing Bean as suggested by RichFaces to display the Tree structure and its folders open / expanded by default when it is first displayed to the User. When I tried to use the Backing Bean I got the 'Import .. cannot be resolved' Error. Also, the Screen shot below. Also, this attribute does not seem to have any effect in the XHTML. Code snippet below:

<rich:treeNode type="fact" adviseNodeOpened="true" iconExpanded="/resources/images/Folder.png" iconCollapsed="/resources/images/Folder.png">

                    #{node.name}

                </rich:treeNode>

I checked in their website (http://docs.jboss.org/richfaces/latest_4_0_X/javadoc/richfaces-components-ui/) as well, and I am not able to find this Attribute in RichFaces 4.x. Is my observation correct? Is there any equivalent way to open the folders by default?

Hi, this question is relevant for me as well.

That was rather useful feature to keep tree opened by condition.

Would it be available in 4.3?
