[octoberdan]

Streamlined example:

        <f:view>
                <h:form>
                        <h:commandButton action="test"/>
                </h:form>
                
                <s:fishEyeNavigationMenu itemWidth="75" itemHeight="75" 
itemMaxWidth="100"
                                itemMaxHeight="100" orientation="horizontal" 
effectUnits="2"
                                itemPadding="10" attachEdge="bottom" 
labelEdge="top">
                                
                        <t:navigationMenuItem icon="images/icon_users.png"
                                        itemLabel="Browse Users" />
                                
                        <t:navigationMenuItem icon="images/computer-wrench.gif"
                                        itemLabel="Browse Projects"/>
                                                
                </s:fishEyeNavigationMenu>      
        </f:view>

resulting exception when I submit:
