[DMN Designer] Do not group V&V messages by UUID ------------------------------------------------ Key: DROOLS-4807 URL: https://issues.redhat.com/browse/DROOLS-4807 Project: Drools Issue Type: Bug Components: DMN Editor Affects Versions: 7.30.0.Final Reporter: Michael Anstis Assignee: Michael Anstis Priority: Major Labels: drools-tools Attachments: V&V.png, dmn1.dmn The V&V results are grouped by UUID. See attached screen-shot. These items are reported individually by {{kie-dmn-validation}} but grouped by {{org.kie.workbench.common.dmn.showcase.backend.validation.ValidationServiceImpl}} in the _standalone_ webapp however I fear Stunner's generic {{ValidationService}} does the same in Business Central and hence reporting DMN V&V per-line may be more troublesum. See [here|https://github.com/kiegroup/kie-wb-common/blob/master/kie-wb-common-...] that should more correctly be:- {code} @Override public Collection<DiagramElementViolation<RuleViolation>> validate(Diagram diagram) { return domainViolations(diagram).stream() .filter(v -> Objects.nonNull(v.getUUID())) .filter(v -> !"null".equals(v.getUUID())) .map(v -> new ElementViolationImpl.Builder().setUuid(v.getUUID()).setDomainViolations(Collections.singletonList(v)).build()) .collect(Collectors.toList()); } {code} h3. Acceptance criteria - Create a DMN file - Add a Decision node with no content - Validate it - Each validation message should be a separate item in the Alert panel
