[ZPT] Problem using ExternalFile with METAL macro

Wed Feb 18 17:31:17 EST 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.

Thanks,
