should be easy ... do something like this:
----------------------
a Java class:
public class RelationshipService {
public static int getID(String guid) {
return 42;
}
}
----------------
a Xtend template:
int getIdForGuid(String guid):
JAVA your.package.RelationshipService.getID(
java.lang.String);
----------
and now you can use xxx.getIdForGuid() as usual
hope it helps

I figured I would create a service I can call:
RelationshipService.getIdForGuid(String guid);
<br>
<br>
<br>
However I can't figure out how to call this service from Xpand :(
<br>
<br>
One way I think could work would be change the source model and add the
RelationshipService service and operation to that model, however I
don't want to pollute the source model with transformation concerns.

So, I'm not too sure where to go next...
