Thiago H. de Paula Figueiredo closed TAP5-739.
----------------------------------------------
Resolution: Won't Fix
This can't be implemented in Tapestry without rewriting it from scratch. Read
the "Principle 1 -- Static Structure, Dynamic Behavior" section of
http://tapestry.apache.org/tapestry5.1/ to know why. Summary: Tapestry has a
static tree of components, and allowing recursion in templates needs dynamic
instantiation of components.
By the way, it's not hard to render trees or tree-like structures inside a
component: just render everything in code. One example:
http://ars-machina.svn.sourceforge.net/viewvc/ars-machina/tapestry-crud/branches/1.1/src/main/java/br/com/arsmachina/tapestrycrud/components/TreeSelect.java?revision=595&view=markup.
> Allow recursion of a component within itself

> Reporter: Seth Call

> Ideally, Tapestry would allow a component to be nested within itself.
> Because recursion of a component within itself is not possible, it is very
> difficult to represent a tree structure, which a component representing each
> node of the tree.
