JET Dynamic UI Variable Types

These 'specific' variable types, specific to each JET metadata provider type, hide the 'factory' detail from the declaration.

Note:

The (requireJS) prefix 'oj-dynamic' must be mapped to the root of the components/providers. Typically, this would be done using the declarative "requirejs" syntax in app-flow.json.

There is no "options" property; all properties are top-level "defaultValue" properties.

Binding Syntax

The binding for these variables is different than typical Visual Builder variables; each of these variables expose the JET metadata provider as a 'provider' property of the variable.

For example, see the "metadata" attribute below:

<oj-dynamic-form id="myForm" class="oj-flex-item oj-sm-12 oj-md-12"
 value="{{$page.variables.formData}}"
 metadata="[[$page.metadata.activities.provider]]">

vb/DynamicLayoutMetadataProviderDescriptor

The following parameters are mutually exclusive:

Parameter	Description
endpoint	A standard Visual Builder endpoint ID, in the form of <service ID> / <operationID>, in an OpenAPI3 document with appropriate JSON Schema type information.
path	A path to a JSON file, which contains a (JET-defined) JSON descriptor for the data.

"metadata": {
  "employee": {
      "type": "vb/DynamicLayoutMetadataProviderDescriptor",
      "defaultValue": {
        "endpoint": "sales/getAllSales"
      }
  },
  "department": {
    "type": "vb/DynamicLayoutMetadataProviderDescriptor",
      "defaultValue": {
        "path": "dynamicLayouts/some/path",
        "operationId": "get_Chickens",
      }
  }
}

vb/ContainerMetadataProviderDescriptor

There is no defaultValue.

"metadata": {
  "myContainerLayoutVar": {
    "type": "vb/ContainerMetadataProviderDescriptor"
  },

vb/HeterogeneousMetadataProviderDescriptor

Parameter	Description
discriminator	The field in the data that contains the options that can be used to determine which metadata provider to use for each new provider.

"metadata": {
  "incidentsProvider": {
    "type": "vb/HeterogeneousMetadataProviderDescriptor",
    "defaultValue": {
      "discriminator": "discriminatorField"
    }
  }
},

vb/ServiceMetadataProviderDescriptor

Parameter	Description
endpoint	A standard VB endpoint ID, in the form of <service ID> / <operationID>, in an OpenAPI3 document with appropriate JSON Schema type information.

"metadata": {
  "employee": {
      "type": "vb/ServiceMetadataProviderDescriptor",
      "defaultValue": {
        "endpoint": "sales/getAllSales"
      }
  }
}

vb/JsonMetadataProviderDescriptor

Requires that 'oj-dynamic' prefix be (requireJS) mapped to the root of the Dynamic UI Components.

The following parameters are mutually exclusive:

• path - path to a JSON file
• data - a (JS) object

"metadata": {
  "employee": {
      "type": "vb/JsonMetadataProviderDescriptor",
      "defaultValue": {
        "path": "path/to/some.json"
      }
  }
}
