Hi Normally you would call the recursive method form a DTML Source. In this source you would write <dtml-let aa=0><dtml-var a></dtml-let>. This gives you a "global" variable. I used it and it works. I would also suggest to use external Python for recursion because DTML-recursion is VERY slow!

Suppose we have a DTML Method named "A" --------------------------------------------------------- <dtml-unless "REQUEST.has_key('aa')"> <dtml-call "REQUEST.set('aa',0)"> </dtml-unless> <dtml-call "REQUEST.set('aa',REQUEST['aa']+1)"> <dtml-var "REQUEST['aa']"> <dtml-if "REQUEST['aa']>10"> <dtml-return "''"><dtml-comment>Stop here</dtml-comment> <dtml-else> <dtml-var A><dtml-comment>Go deeper</dtml-comment> </dtml-if> --------------------------------------------------------- Excute it, then got the result: Error Type: KeyError Error Value: validate --------------------------------------------------------- This is a sample method abstracted from my another more complex method which works in the previous version of Zope. I know that there are something changed in the SecurityManager. But I have no idea how to make this sort of recursive method works again. Any suggestion? Thanks.
