Lookup References in Header and Footer Elements not Resolving #60

Closed drj826 closed 8 years ago

drj826 commented 8 years ago

When I put a lookup reference in a header or footer element, it does not get resolved. For instance:

header_left:: [lookup:date:sml-ug]

should place the date of the SML User Guide document (ID = sml-ug) in the left header. But the lookup reference does not get resolved and 

[lookup:date:sml-ug]
is displayed instead.

This is actually not a problem. The problem is that I was not writing the template correctly to retrieve the looked up value. Here's an example of how to do it right. Consider the following document. Notice the 'header_left' element:

>>>DOCUMENT.sml-ug
title:: Semantic Manuscript Language (SML)
subtitle:: User Guide
abbreviation:: UG
author:: Don Johnson
copyright:: 2002-2015, Don Johnson
doctype:: book
header_left:: [lookup:date:sml-ug]
logo_image_small:: files/images/sml_logo.png
logo_image_center:: files/images/meadow.jpg
version:: v2.0
.
.
.

The correct way to access the header value in a template is:

[%- IF library.has_property(document_id,'header_left') -%]
[%- header_left_element = library.get_first_property_value_element(document_id,'header_left') -%]
[% INCLUDE part_list.tt self = header_left_element %]
[%- END -%]
