Hi Reinhold, Here's a go at answering your problem. I gather you don't even need a component as such - just a piece of code to perform a calculation. I borrowed a technique from SchoolBell which may help. I think it may help because it provides a way of performing any variety of python code within a tal template without using python in the template. Any method added to TFWSAPI can be accessed in tal with 'tfws:mymethod'. I've not used XMLRPC calls with Zope so I'm not sure how it will translate. Good luck. Best regards, Darryl <!-- gives all sorts of lovely custom TAL expressions --> <zope:adapter for="*" name="tfws" provides="zope.app.traversing.interfaces.IPathAdapter" factory=".tfwsapi.TFWSAPI" /> class TFWSAPI(object): """TALES function namespace for TFWS specific actions.
