New subject: [Zope] Problem using ExternalFile with METAL macro

18 Feb 2004

      I'm unable to get ExternalFile to work with macros within page templates 
and I'm hoping that some of you have solved this problem.

I'm a newbie to Zope, so it's quite possible it's my error, but I've been 
struggling with this for a while & haven't been able to find anything 
online about my problem.

I have an ExternalFile set to behave like a page template called index_html 
and it calls a macro, m1, in another ExternalFile, mac1, which is also set 
to behave like a pt. In brief I get the following error:

Error Type: AttributeError
Error Value: macros

Note that if the same macro is included in a "real" page template, no error 
occurs. Likewise an error occurs regardless of whether index_html is a 
"real" pt or an ExternalFile behaving like one.

I've included the files themselves and the traceback from the error_log below.

index_html:

<html>
   <head>
     <title tal:content="template/title">The title</title>
   </head>
   <body>
     <table metal:use-macro="here/mac1/macros/m1"></table>
   </body>
</html>

mac1:

<div id="footer"  metal:define-macro="m1" >
hello, world
</div>

Traceback (innermost last):

I'm running ExternalFile 1.2, with Zope 2.6 on a box running roughly the 
latest version of SuSE Linux, and Python 2.1.3.

Any insight you have into this problem would be most appreciated.
