Fixes an issue where fields like control weight on ControlNet nodes and image on IP Adapter nodes didn't render.
These are "single or collection" fields. They accept a single input object, or collection. They are supposed to render the UI input for a single object.
In a7a71ca935 a performance optimisation for a hot code-path inadvertently broke this.
The determination of which UI component to render for a given field was done using a type guard function for the field's template. Previously, this used a zod schema to parse the template. This is very slow, especially when the template was not the expected type.
The optimization changed the type guards to check the field name (aka its type, integer, image, etc) and cardinality directly, without any zod parsing.
It's much faster, but subtly changed the behaviour because it was a bit stricter. For some fields, it rejected "single or collection" cardinalities when it should have accepted them.
When these fields - like the aforementioned Control Weight and Image - were being rendered, none of the type guards passed and they rendered nothing.
The fix here updates the type guard functions to support multiple cardinalities. So now, when we go to render a "single or collection" field, we will render the "single" input component as it should be.
This fixes the broken readiness checks introduced in the previous commit.
To support async batch generators, all of the validation of the generators needs to be async. This is problematic because a lot of the validation logic was in redux selectors, which are necessarily synchronous.
To resolve this, the readiness checks and related logic are restructured to be run async in response to redux state changes via `useEffect` (another option is to directly subscribe to redux store). These async functions then set some react state. The checks are debounced to prevent thrashing the UI.
See #7580 for more context about this issue.
Other changes:
- Fix a minor issue where empty collections were also checked against their min and max sizes, and errors were shown for all the checks. If a collection is empty, we don't need to do the min/max checks. If a collection is empty, we skip the other min/max checks and do not report those errors to the user.
- When a field is connected, do not attempt to check its value. This fixes an issue where collection fields with a connection could erroneously appear to be invalid.
- Improved error messages for batch nodes.
Board fields in the workflow editor now default to using the auto-add board by default.
**This is a change in behaviour - previously, we defaulted to no board (i.e. Uncategorized).**
There is some translation needed between the UI field values for a board and what the graph expects.
A "BoardField" is an object in the shape of `{board_id: string}`.
Valid board field values in the graph:
- undefined
- a BoardField
Value UI values and their mapping to the graph values:
- 'none' -> undefined
- 'auto' -> BoardField for the auto-add board, or if the auto-add board is Uncategorized, undefined
- undefined -> undefined (this is a fallback case with the new logic)
- a BoardField -> the same BoardField
