Resolution: Invalid

Please reopen the bug *only* if you are getting out of memory exceptions. From the history, it looks like it was reopened because you want support for recursive components; that would be a new feature, not a bug.

> Key: TAP5-134
> URL: https://issues.apache.org/jira/browse/TAP5-134
> Project: Tapestry 5
> Issue Type: Bug
> Environment: MacOSX 10.4.8, Eclipse 3.2.1
> Reporter: Randy Leonard
> Assignee: Howard M. Lewis Ship

> 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
> location
> classpath:org/example/hilo/components/MenuCell.html, line 4, column 23
> org.apache.tapestry.ioc.internal.util.TapestryException
> Java heap space
> location
> classpath:org/example/hilo/components/MenuCell.html, line 4, column 23
> java.lang.OutOfMemoryError
> Java heap space
