Model not found

Error message

Model not found

What it means

Thrown by updateExistingModel after passing the originalId check but finding that modelManager.getModel(form.value.originalId) returns undefined. The edit session is well-formed but the target model vanished from the registry between opening the form and saving it.

Solutions

1. Catch this error and offer to save as a new model instead of updating
2. Refresh the models list when the edit window regains focus, warning if the target disappeared
3. Compare editingModelId with the fresh list before save; if missing, prompt the user
4. Ensure model ids are stable across persistence rounds (don't regenerate keys on load)

Example fix

// before
const existingConfig = await modelManager.getModel(form.value.originalId)
if (!existingConfig) throw new Error('Model not found')

// after
const existingConfig = await modelManager.getModel(form.value.originalId)
if (!existingConfig) {
  form.value.originalId = undefined
  return createNewModel() // degrade to create
}

const stillThere = (await modelManager.getModel(form.value.originalId)) != null
if (!stillThere) { /* offer save-as-new or abort */ }

null

try { await updateExistingModel() } catch (e) { if (String(e?.message) === 'Model not found') { form.value.originalId = undefined; await saveForm() /* recreates */ } else throw e }

When it happens

Trigger: Saving an edit after the model was deleted elsewhere (another tab, another component, external config file edit). Also when the store was reloaded and the model id changed (regenerated key) or when persistence failed silently.

Common situations: Long-lived edit dialog over a model deleted in the meantime; concurrent edits from two windows; external modification of the models config file; id regeneration on app upgrade.
