Actually, they used to, but they do not anymore and can participate in
recursion. See http://issues.apache.org/jira/browse/TAPESTRY-654?page=all.
The following works well, for example:
<comp jwcid="@RenderBlock" block="ognl:components.subMenuItems"/>
<comp jwcid="[EMAIL PROTECTED]">
<comp jwcid="@For" source="ognl:menuItems" value="ognl:menuItem">
<comp jwcid="@Insert" value="ognl:menuItem.fullName"/><br/>
<comp jwcid="@If" condition="ognl:menuItems != null">
<comp jwcid="@Insert" value=" "/>
<comp jwcid="@RenderBlock"
block="ognl:components.subMenuItems"/>
</comp>
</comp>
</comp>

In case of recursion this is often unacceptable. But caching can be
specified only in the component specification, not per binding.
This means that when one had to use recursion it is necessary to write
own recursion-safe Foreach, If, etc. components as well.

Subject: Re: circular references to components?
This seems kind of contrary to the good design seen in other parts of
tapestry. Is this going to be changed at all in the future? Recursion
seems like something that should not required a hack.

Hi,
No, it can't you have to use Block/RenderBlock see :
