[stringtemplate-interest] Question about using a separate Group file from within a group

[Richard Martin]

Hello, I don't think that title is a very good overview so I will try here.

I have an inheritance tree for my pages such as

Folder called siteA contains siteA templates such as :
Base.stg - outline of page that uses regions to fill in gaps
Page1.stg that extends Base.  - defines the missing bits in the middle.
Page2.stg that extends Base.  - same as 1 but with different things.

With multiple sites and pages I want to be able to call another
template group, generic.stg.  Doesn't need an inheritance tree.  So I
can go like this from inside an overriding region on page1 -
$doSomethingGeneric(paramA, paramB, paramC)$ and have it call a
template method from generic.stg.

I have loaded the generic folder and the site folder into a
templateGroupLoader.  Is it possible for me to call template methods
on generic from within a page template group?

Cheers
Bob
