Hello *,
cross references are great. I played with them in the last minutes. But I search
a more lazy way for usage. Example (XText) :
===
Service :
'service' name = ID '{' '}';
Invoke :
'invoke' action = [Service|ID] ';';
===
DSLs code:
===
service one {}
service two {}
invoke one;
invoke two;
===
But there are more services than written in this file. However, it would be
great, if "invoke (one|two);" would be an proprosal. An "invoke three;" should
be no error in the generated editor.
How can I modify my grammar for this?
Ciao, Micha

Hi Michael,
in this case I'ld advise you to not use cross references but plain text
instead. You can use validation rules to provide feedback for the user.
Another possibility is to create the services on demand when a link
should be resolved. Note that this is a tough task and requires
detailled knowledge about the architecture and lifecylce. But this way
round it would be easier to provide content assist for available services.
Regards,
Sebastian
