But it works correctly after I click the html radio button.\n\nIt works for initial state if i use plain string for value, ie: `value=\"closed\"`\n\nEnum values work OK in reactive forms, but not with signal forms.\n\nExample link bellow.\n\nBest regards.\n\n\n### Please provide a link to a minimal reproduction of the bug\n\nhttps://stackblitz.com/~/github.com/kle-pra/signal-form-enums?file=package.json\n\n### Please provide the exception or error you saw\n\n```true\n/\n```\n\n### Please provide the environment you discovered this bug in (run `ng version`)\n\n```true\nAngular CLI       : 21.0.5\nAngular           : 21.0.7\nNode.js           : 24.11.0\nPackage Manager   : npm 11.6.3\nOperating System  : linux x64\n\n┌───────────────────────────────┬───────────────────┬───────────────────┐\n│ Package                       │ Installed Version │ Requested Version │\n├───────────────────────────────┼───────────────────┼───────────────────┤\n│ @angular-devkit/build-angular │ 21.0.5            │ ^21.0.5           │\n│ @angular/build                │ 21.0.5            │ ^21.0.5           │\n│ @angular/cli                  │ 21.0.5            │ 21.0.5            │\n│ @angular/common               │ 21.0.7            │ 21.0.7            │\n│ @angular/compiler             │ 21.0.7            │ 21.0.7            │\n│ @angular/compiler-cli         │ 21.0.7            │ 21.0.7            │\n│ @angular/core                 │ 21.0.7            │ 21.0.7            │\n│ @angular/forms                │ 21.0.7            │ 21.0.7            │\n│ @angular/language-service     │ 21.0.7            │ 21.0.7            │\n│ @angular/localize             │ 21.0.7            │ ^21.0.7           │\n│ @angular/platform-browser     │ 21.0.7            │ 21.0.7            │\n│ @angular/router               │ 21.0.7            │ 21.0.7            │\n│ @angular/service-worker       │ 21.0.7            │ 21.0.7            │\n│ rxjs                          │ 7.8.2             │ 7.8.2             │\n│ typescript                    │ 5.9.3             │ 5.9.3             │\n│ zone.js                       │ 0.16.0            │ ~0.16.0      \n```\n\n### Anything else?\n\n","author":{"url":"https://github.com/kle-pra","@type":"Person","name":"kle-pra"},"datePublished":"2026-01-08T13:37:04.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/66402/angular/issues/66402"}
