[DMN Designer] Highlight invalid DRGElements -------------------------------------------- Key: DROOLS-3657 URL: https://issues.redhat.com/browse/DROOLS-3657 Project: Drools Issue Type: Enhancement Components: DMN Editor Reporter: Michael Anstis Assignee: Guilherme Gomes Priority: Major Labels: drools-tools Whenever a DMN file is validated (be it when the Project is compiled or via the Validate button on the toolbar) the DMN editor should highlight issues reported by the validation. This should include DRG nodes (on the graph view) or DRGElements (in the Boxed Expression, aka grid, view). The nature of the highlighting is to be defined; but probably consists of an orange background for warnings and red background for errors; possibly both with a warning triangle positioned somewhere. UX will need engaging for design proposals.
