TYPO3.Fluid

I tried to build some kind of tree by invoking a section/for recurse.

Template:
<f:section name="children">
<f:for each="{parent.children}" as="child"> {indent}
Child: {child.name}
- #{child.objectUuid}
- <a href="<f:uri.action action='deletenode' arguments="{parent:parent,child:child}" />">Delete</a>
- <a href="<f:uri.action action='createnode' arguments="{parent:child}" />">Create new child</a><br />
<f:render partial="admin_index_nodelist" section="children" arguments="{parent:child, indent:indent}" />
</f:for>
</f:section>

Tried to remove a variable "child" which is not stored in the context!
