Hi,

I just came across a little problem. Following query:

self.ownedElements->select(e | e.stereotypes->exists(s | s.name = "singleton"))->collect(e | e.name)

in Xtext OCL console fails with:

Evaluating:
self.ownedElements->select(e | e.stereotypes->exists(s | s.name = "singleton"))->collect(e | e.name)
Results:
Parsing failure
null
1: missing EOF at '('
1: Unresolved Property 'unknown-type::select'

which might be a bit misleading. The "old" OCL console correctly reports the problem:

Evaluating:
self.ownedElements->select(e | e.stereotypes->exists(s | s.name = "singleton"))->collect(e | e.name)
Results:
Usage of non-standard quoted element name: "singleton"

It this well-known issue?

Regards,
Filip

Hi Filip

Please raise a Bugzilla.

Maybe we can do better, but error reporting/recovery is not one of
Xtext's best features.
