[stringtemplate-interest] filling a field ($...$) with data that also contains a (part of) a field ($...$test)

[Jonathan Buhacoff]

I worked on a project where I had a similar setup.

I was able to render in just one pass by wrapping each value from the  
database with an ST object before adding it to the primary template's  
attributes.

Try  setAttribute(name, new StringTemplate(GetData());  ... as long as  
the return value of GetData() is actually valid template text.  If  
it's something else you'll have to recurse.

In my project I wrote a custom STG that wraps my values in ST on the  
fly.
