DF0040: JSON-Render View Used After Disposal

Message

JSON-render view "{id}" was used after it was disposed.

Cause

view.dispose() unregisters the view's shared state and its broadcast listeners. Calling update or patchState on a disposed handle is a lifecycle bug — the shared state it targeted no longer exists.

Example

const view = createJsonRenderView(ctx, { id: 'metrics', spec })
view.dispose()
view.update(nextSpec) // DF0040

Fix

Create a fresh view with createJsonRenderView instead of reusing a disposed handle. The id is free to reuse once disposed.

• packages/json-render/src/node/create-view.ts — update / patchState throw this after dispose().
