Hi!
Did you find a solution to your problem? I suspect that one possible
solution may reside in the qualifiedName rule.
Make sure that it doesn't return a tree. Another solution might
involve redoing the importDeclaration rule in your original
grammar that makes the AST.
In your grammar that defines importDeclaration as two rules:
tempRule : '.' '*' ;
importDeclaratrion : ('import' qualifiedName '.')=> 'import'
qualifiedName tempRule+ ';'
-> ^('import' qualifiedName tempRule+ ';')
| 'import' qualifiedName ';' -> ^('import'
qualifiedName ';')
You can then follow each branch with the tree you want.
hth,
Bernardo
