 {"id":"smartfiles-vap","title":"Missing Platform.runLater in ApplicationInteractor event handlers","description":"In ApplicationInteractor.java, most event handlers correctly use Platform.runLater() to update the model on the JavaFX Application Thread. However, two handlers do not:\n\n- handleDocumentTagAddedEvent (line 49-51) calls model.updateDocumentTags() directly\n- handleArchiveEntryAddedEvent (line 61-64) calls model.addDocumentFromArchiveEntry() directly\n\nSince Spring events can be published from any thread, these could cause UI updates from non-FX threads, leading to race conditions or crashes.\n\n**Fix:** Wrap these calls in Platform.runLater().","status":"closed","priority":1,"issue_type":"bug","created_at":"2026-01-15T22:32:45.051937+01:00","created_by":"abedurftig","updated_at":"2026-01-16T20:58:09.470451+01:00","closed_at":"2026-01-16T20:58:09.470451+01:00","close_reason":"Closed"}
