Hi all,

I have two different resource (referenced DSL one to other) .

I have two different dsl :
such as :

Web returns Web:
'Web'
name=QualifiedName
'{' ('sitePermission' '=' sitePermission = [user::SitePermission|QualifiedName])?

SitePermission is defined other dsl :

UserModel returns UserModel:
'UserModel' name = QualifiedName '{'
('sitePermissions' '{' sitePermissions+=SitePermission (sitePermissions+=SitePermission)* '}' )?
'}'
;

I use SitePermission Object for referenced automatically.
User must not enter manually.

Related code :
SitePermission s= sitepermission6.createDefaultSitePermission(contentUnitNames.get(index),guid);
sitepermission6.loadForCreateSitePermission(rootWeb, s);
rootWeb.setSitePermission(s); // this initialization is give error Sad.

Hence not come qualifiedname. such as UserModel.SP must come but onlly come SP. and I do not give string for setSitePermission already.

I am aim :I must do it : give reference automatically ,not use CTRL+SPACE .is it possible with XTEXT?

Best regards

Hi

the Problem is as follows:

Junior want (automatically/on autoedit/save/<similar hook>)

- create a new Instance of an EObject in a different Resource.
- create a reference to this EObject in the current Resource.

Using Content Assist or a Quickfix is not an Option (it should be 100% automatic)

Hi,

as said before: the problem to solve is:

- what todo to fulfil your requirements
- and not: how to i get rid of the exception (that says that the stuff is not in scope - probably cause it is not indexed)

as i said: i am not able to tell if your way of solution is the right one and can ever work.
this is why i asked you to ask a new question on how to solve your business problem.
maybe then i can tell sebastian or sven to have a look.
