[Zope] new browser window doesn't show content

[Santagostino Pretina, Luca]

Hi list,
I've got this prob I cant seem to solve:
got two macros:

first one called "main" applies a filter :


<div metal:define-macro="main"
tal:define="auth_filter nocall: modules/ZTUtils/LazyFilter">

  <div tal:define="raw_items python: here.contentValues(
		filter={'Type':( 'Article'
                            ) } );
items python: auth_filter( raw_items, skip='' );
">

and second one simply shows some content:

<table tal:condition="here/contentValues" width="100%" border="0"
cellspacing="0" cellpadding="4">
<tr tal:repeat="item here/contentValues"> 


The problem is that they work fine if I access through the "test" link, but
If I open a new browser window the first one ("main") it doesn't show me
anything...

Why does that happen? what do I have to do?

Need help please,
thanks a lot
Luca
