Example 62 with Issue

use of org.eclipse.xtext.validation.Issue in project n4js by eclipse.

            // cause a multitude of follow-up exceptions in many @Check methods (could easily be hundreds). Since,
            // EMF/Xtext has the behavior of not aborting the overall validation due to an exception in a single
            // @Check method, this will lead to many exceptions, which are all just follow-up issues of the problem
            // that caused the post-processing to fail.
            // 1) Since this is annoying and misleading, we just ignore all ordinary validation.
            // 2) To not overlook the problem, we create a single validation issue (error) pointing out the problem.
