if you mean cross refs from test.mydsl to other.mydsl:
this works out of the box if you do proper naming/referencing (and have build automatically on)

if you mean something else: please elaborate

My file extension is jpl and I have two files like test1.jpl and test2.jpl. test1.jpl contains "call test" and test2.jpl contain "proc test". While click on "call test" it is not going to "proc test". If both are in same page it is working. And my project auto build is enabled.

are you sure the naming is proper? if you use the "open model element dialog" from the navigate menu, what is the names of the procs?

can you please share a small example based on the hello world grammar from the last time with

- the grammar you use
- both model file

It is working in new project with simple grammar like:

Call: 'call' ref=[Proc];

Proc: 'proc' name=ID;

But is not working for :

Call: 'call' ref=[Proc]('(' (exp+=Expression (','? exp+=Expression)*)? ')')?;

Proc: ('string'|'double')? ('proc') name=ID('(' (exp+=Expression (','? exp+=Expression)*)? ')')?;

sure you have build automatically on? and have built the project?
did you disable the builder in your language?
what does the dialog show with the hello world example?

then there must be some customization in your code that prevents that

- IQualifiedNameProvider
- IDefaultResourceDescriptionStrategy

.....

and double check you have build automatically on, the project having xtext nature and did a clean build in the workspace
