Hi all: I'm trying to nest several macros but only the last is showed. I define for example macroA with a slot named slotA for example. macroB uses macroA and fills slotA, but also defines a slot.. something like this: ----------------- MacroA <html xmlns="http://www.w3.org/1999/xhtml" xmlns:tal="http://xml.zope.org/namespaces/tal" xmlns:metal="http://xml.zope.org/namespaces/metal" metal:define-macro="macroA"> <head> <span metal:define-slot="slotA"> </span> ----------------- MacroB <div xmlns:metal="http://xml.zope.org/namespaces/metal" metal:use-macro="container/macroA/macros/macroA"> <span metal:fill-slot="slotA"> <div align="center" metal:define-macro="macroB"> <span metal:define-slot="slotB"></span> </div> </span> </div> -----------------Page And last I use the macroB with: <div xmlns:metal="http://xml.zope.org/namespaces/metal" metal:use-macro="container/macroB/macros/macroB"> <span metal:fill-slot="slotB"> <br>Hello! </span> </div> I think all the process is as follows: Page calls macroB, macroB calls macroA, and all the code is rendered, the problem is only the code inside macroB is rendered... It's posible to nest macros this way? Greetings.
