Hey Daniel,
I read the reply and tried creating a TemplateDirectiveModel to handle it
as you suggested. It seemed cleaner than calling internal freemarker
methods. The issue I ran up against was that when rendering the final
output it would miss model attributes that were defined in the external
template.
So this would work:
<@content name='help.h2'>
<#assign test='A test string'/>
This is a test: ${test}
But this would not:
<#assign test='A test string'/>
<@content name='help.h2'>
This is a test: ${test}
Using my original code I was able to solve that by defining the macro as below:
<#macro content name>
<#local temlateSource = hd.processElement(name)/> <-- This calls
the code I originally sent you to get the nested content as a String
or pull it from the DB if available.
<#local inlineTemplate = temlateSource?interpret/>
<@inlineTemplate/>
I think because of that I'm going to have to stick with my original
method. Unless I can replicate what macro is doing to get the full
model from the environment.
