[Xpand] expand in a dynamic binding manner [message #643538]

Hi again,

is there a way to specify an EXPAND and let it related to different DEFINE sections due to dynamic binding? Consider the following grammar rule:

WebPage: 'page' name=ID '{' contents+=AbstractContent* '}';
AbstractContent: (Chapter | Image | Paragraph); ...etc.

I would like to do simething like:

«EXPAND content FOREACH this.contents»
«DEFINE content FOR Chapter» ... «ENDDEFINE»
«DEFINE content FOR Image» ... «ENDDEFINE»
«DEFINE content FOR Paragraph» ... «ENDDEFINE»

An alternative but quite ugly way is to check "this.eClass().name" on a content entry and to redirect to a certain DEFINE.

Thanks in advance,
Stefan

Well, this seems to be implemented already. However, you have to have a (useless) rule for the "abstract rule" as well:

«DEFINE content FOR AbstractContent»
«ENDDEFINE»

With this, it is working!
