Description

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.
