Hi all,
I've recently run into a problem that I am struggling to figure out.
I will try and keep this as short and as clear as possible, so here goes:
I have an Xtext model in which I describe an object, say Application:
Application:
'application' name=ID '{'
('description' description=STRING ';')?
'applicant' 'id' applicantId=STRING ';'
('applicant' applicant=[Applicant|FQN] ';')?
'}'
;
At the moment Applicant is very simple, just a single element with a description field.
Now I also have a validation configured that checks that my application either has a value for the application id OR a valid reference to an applicant. Neither of these two are mandatory, but at least one must be present.
So to simplify, the check looks like this:
@Check
public void checkAtLeastIdOrApplicantExist(Application application) {
if (application.getApplicantId().isEmpty() || application.getApplicant() == null) {
//create error;
}
}
Now I've added some unit tests around this and I've found something that I don't quite understand and haven't found documented anywhere..
If I run a test with an application that refers to a null applicant and no application id everything is fine, I hit the breakpoint and a validation issue gets created.
BUT, if I run a test with an application that has no application id BUT it has a reference to an invalid, non-existing applicant, I get a 'dangling reference' issue but the actual check above never gets executed?! I would prefer to have both, but am only getting the dangling reference error....
Is this some feature (and is there a way to disable it) or is something else the issue?
Thanks for your help!

Hi Aleks,
do you use an imported EPackage or a generated pacakge? It seems that
your model is inconsistent. Do you have other checks defined? Do you
modfiy the model by accident somewhere in the validation? Without a
concrete sample model and some more code it's hard to guess what's going
wrong.
Regards,
Sebastian
