[ZPT] Permanently reversed PARENTS... A Bug?

[Felix Hermann Hoßfeld]

Hi!

I was looking for an equivalent of <dtml-var ... reverse> in order to put 
breadcrumbs on the page.

I don´t want to reverse the request.PARENTS permanently so I like to copy it 
before reversing to itemlist.

<span tal:define="itemlist request/PARENTS; dummy itemlist/reverse"
tal:repeat="item itemlist">
Breadcrumbs here
</span>

However, this still reverses request.PARENTS. I guess itemlist is only a 
pointer to request.PARENTS, not a copy. Is that how tal:define is supposed 
to work?

A workaround is simple. You only need to reverse the list once more. But a 
clean solution would be better.

Yours

Felix
