fishEyeNavigationMenu throws exceptions when forms submit

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:

I just found the solution.
<s:fishEyeNavigationMenu> should be inclosed in <h:form>
