[antlr-interest] String template return val propagation

Hi all
I have the following grammar fragment (with template output) that
parses an AST and translates it to a text representation. The parsing
works fine and I'm reading in the template group just fine.
The problem that seems to be happening below is that 'prefixed_name'
is being correctly recognized and the template returned, but the
'name' production is not passing that template back up to the 'name'
non-terminal in the top rule for inclusion in the template rewrite.
Is there some switch I'm forgetting to set or do I need to do
something explicit with the second rule to make sure the template gets
propagated.
Thanks in advance
text_block
: ^(AS_TEXT name phrase+)
-> text(name={$name.st})
;
name
: prefixed_name
;
prefixed_name
: ^(AS_NAME AS_NAME_NS AS_NAME_LOCAL)
-> name(ns={$AS_NAME_NS.text},local={$AS_NAME_LOCAL.text})
;
