> Embedding a recursive reference to a component within an html template causes a stack overflow.  Example menu component is as follows:
> <tr xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd">
> 	<td>
> 		<t:comp type="Iff" test="prop:menuItem.isSelected">
> 			<b>${menuItem.name}</b>
> 			<t:comp type="Iff" test="prop:menuItem.containsSubMenu">
> 				<t:comp t:type="menu" menuHierarchy="menuItem.subMenu"></t:comp>
> 			</t:comp>
> 		</t:comp>
> 		<t:comp type="Iff" test="prop:menuItem.isSelected" negate="true">
> 			<a t:type="PageLink" page="prop:menuItem.pageName">${menuItem.name}</a>
> 		</t:comp>
> 	</td>
> </tr>
> The menu component works fine if the recursive if the recursive reference is removed.  The error seems to take place at startup, not at render time.
> Error message displayed in browser is as follows:
> A runtime exception has occurred.
> org.apache.tapestry.ioc.internal.util.TapestryException
> Could not convert 'menuItem.name' into a component parameter binding: Java heap space
