PrimeFaces Tree component, setting selected node from managed bean

Question

I\'m running Primefaces 3.2 and JSF 2.0 on Glassfish 3.

I\'ve tried a lot, to programatically set the selected node from a managed bean. That includes setting the se

Answer 1

In the above if statement, when true, do a node.setSelected(true);

I use that to set nodes on as required. The reverse obviously has the reverse effect; it turns them off. My use case has been a boolean check box to turn all nodes on or off as I have quite a few running down the side of a tree. My actual code, involving a few methods, is therefore:-

public Boolean getSelectionState() {
    return selectionState;
}

public void setSelectionState(Boolean selectionState) {
    this.selectionState = selectionState;
}

public String getSelectLabel() {
    return selectionState ? "De-select all" : "Select all";
}

/**
 * Flips all nodes on or off depending on checkbox.
 */
public void onSelectChange() {
    if (prefs.isDebug()) {
        LOG.log(Level.INFO, "Value change event occured. Selection state is:{0}", selectionState);
    }
    for (TreeNode node : rootNode.getChildren()) {
        node.setSelected(selectionState);
    }
    nodes = new ArrayList(rootNode.getChildren());
    selectedNodes = nodes.toArray(new TreeNode[nodes.size()]);
    mapDevices();
}

I am however, using 3.4 on JSF 2 on GF 3. I don't know if there is a difference.
