CSSListMenuDisplayer doesn´t seem to be handling correctly menu tags without location, action or page:

    <Menu name="admin" title="Administration" toolTip="Administration tasks" >
<Item title="Budget Lines" toolTip="Budget lines management" page="/budgetLines.jsp" />
<Item title="Workflow history" toolTip="View workflow history of a request" page="/viewWorkflow.jsp" />
    </Menu>

In the example, the main component 'admin' has not location, page or action. If you use this definition will obtain this (note the 'null' string in the href of 'Administration'):

<ul id="primary-nav" class="menuList">
<li class="menubar">
<a href="null">Administration</a>
<ul>
<li><a href="/e-SCP/budgetLines.jsp" title="Budget lines management">Budget Lines</a></li>
<li><a href="/e-SCP/viewWorkflow.jsp" title="View workflow history of a request">Workflow history</a></li>
</ul>
</li>
</ul>

I have been viewing the CSSListMenuDisplayer class and I have seen some suspicious code. For example, there is a strange concatenation of if clauses at the beginning of the displayComponents method:

protected void displayComponents(MenuComponent menu, int level)
    throws JspException, IOException {
        MenuComponent[] components = menu.getMenuComponents();

        if (components.length > 0) {
            // if there is a location/page/action tag on base item use it
            if (components.length == 0){
            ...


Thanks in advance
