[antlr-interest] ANTLRworks or eclipse plugin vs. composite grammars

[Andreas Meyer]

Hi!

Is there anybody on the list that has a composite grammar, and 
successfully works with it using an Ecliplse plugin or ANTLRworks? With 
successful, I mean:

* highlight ambiguities, that span multiple grammars in the import hierarchy
* navigate from one grammar to another, using something like "open 
declaration" in Eclipse (it seems to work in single-grammar mode, but 
not with composite grammars)
* saving/auto-building one of the included grammars, without the tool 
complaining about undefined rules (because it should not try to re-build 
an included grammar)

I'm just wondering if I do something wrong, or if those features are 
just not implemented yet. Note that I dont want to complain and ask 
"implement it!", just for curiosity.

Best,
Andreas
