[2.0.0-rc1] Compatibility with XB

No error? That s'great news. I will check again.

By the way, I know they are still very early stage, and I don't expect the builder to work properly, I just want the 2 JSON schema resolvers ($ref: ui-patterns:// and $ref: json-schema-definitions://) to work well together.

No, it doesn't work.

Using XB components in UIP2

• I install both ui_patterns_library and experience_builder
• I got to /admin/appearance/ui/components/experience_builder/shoe_button
• icon prop has this unknown prop type: {"$ref":"json-schema-definitions:\/\/experience_builder.module\/shoe-icon","type":"object"}

According to https://git.drupalcode.org/project/experience_builder/-/blob/0.x/schema.... the expected resolved json schema must be

title: Icon
type: object
properties:
  name:
    type: string
    title: Name
    default: primary
    enum:
    - moon-stars-fill
    - moon-stars
    - star-fill
    - star
    - stars
    - rocket-fill
    - rocket-takeoff-fill
    - rocket-takeoff
    - rocket

Which will be loaded as Enum prop by UIP2.

So, what is happening? Why the JSON schema reference is not resolved?

• It is broken on Experience Builder side?
• Is it broken because of having XB & UIP2 together?

Using UIP2 components in WB

I was not able to test because XB is currently broken:

Symfony\Component\Routing\Exception\RouteNotFoundException: Route "experience_builder.experience_builder" does not exist. in Drupal\Core\Routing\RouteProvider->getRouteByName() (line 211 of core/lib/Drupal/Core/Routing/RouteProvider.php).

Let's try later.

Using XB components in UIP2

The issue was on UIP2 side. Fixed by Christian in https://git.drupalcode.org/issue/ui_patterns-3490873/-/commit/51c4ea3e22...

But he needs to add some tests.

Using UIP2 components in WB

We are not able to test because XB is currently broken (not the same bug as yesterday...). Let's wait a bit and pull again.

Today, we decided to merge this issue because the Using XB components in UIP2 fix is enough for RC1 (after adding some tests, right?).

About Using UIP2 components in XB:

• It seems XB is not resvolving $ref: ui-patterns:// but it may not resolved "$ref":"json-schema-definitions: either, so let's wait they implement a working reference resolver
• when both XB and UIP2 are installed, XB is raising errors, so our component plugin manager decorators may not be fully compatible
• XB is not loading UIP2 components (!) but is loading the ui_patterns_blocks's blocks twice, because of our (UIP2) context management; we derivate blocks twice, one with entity context and one without

Let's create a 2.1.0 issue.

    $values = array_filter($values, fn($value) => !is_null($value) && $value !== '');

Why are you removing the empty values? They can be legit in some enumerations. Is removing only the null values enough?

We need to remove empty strings if they are not part of the enum list. Propably we should remove all values which are not part of the enum list

It is nice to do it in the source plugin, but the prop type plugin have a ::normalization() method.

Not sure if "ref" is often used in SDC right now without custom stream wrappers like xb is doing.

There are 2 ways of using the JSON Schema $ref system AFAIK:

• With a custom stream wrapper like we do in UI Patterns 2 (ui-patterns:// with StreamWrapper) and Experience Builder (json-schema-definitions:// with JsonSchemaDefinitionsStreamwrapper)
• With simple URI retrieval when the URI is dereferencable: http(s), file, ftp...
