The UtilityNetworkAssociationsElement defines how utility network associations can participate in the form.

Example

// Configure associations in forms
const formTemplate = new FormTemplate({
  title:"My Associations",
  description: "Provide information for feature",
  elements: [{ // Autocasts to new UtilityNetworkAssociationsElement
    type: "utilityNetworkAssociations",
    label: "Inspector Information",
    description: "Field inspector information",
    associationTypes: [
      {
       type: "content",
       title: "myContents"
      },
      {
       type: "container",
       associatedAssetGroup: 2,
       associatedNetworkSourceId: 5,
       associatedAssetType: 3
      },

associationTypes

autocast Property

Type: UtilityNetworkAssociationType[]

The association types.

declaredClass

readonlyinherited Property

Type: string

Inherited from: Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

description

inherited Property

Type: string | null | undefined

Inherited from: Element

The element's description providing the purpose behind it.

editableExpression

Property

Type: string | null | undefined

A reference to the ExpressionInfo.name of an Arcade expression defined in the FormTemplate.expressionInfos of the FormTemplate. The expression must follow the specification defined in the Form Constraint Profile. Expressions may reference field values using the $feature global input and must return either true or false.

When this expression evaluates to true, it is possible to edit the field value, and vice-versa if false. If the referenced related table is not editable, the editable expression is ignored and the element is not editable.

The referenced expression must be defined in the form template's FormTemplate.expressionInfos. It cannot be set inline within the element object.

Form Constraint Arcade Profile

label

inherited Property

Type: string | null | undefined

Inherited from: Element

A string value containing the field alias. This should not be used for referencing fields in Arcade expressions. Rather, the service FieldElement.fieldName should be referenced.

type

readonly Property

Type: "utilityNetworkAssociations"

Indicates the type of form Element.

visibilityExpression

inherited Property

Type: string | null | undefined

Inherited from: Element

A reference to the ExpressionInfo.name of an Arcade expression defined in the FormTemplate.expressionInfos of the FormTemplate.

When this expression evaluates to true, the element is displayed. When the expression evaluates to false the element is not displayed. If no expression is provided, the element is always displayed. Care must be taken when defining a visibility expression for a non-nullable field as to make certain the specified field has either 1) a default value, or 2) is made visible to the end user to enter a value before submitting the form.

The expression must follow the specification defined in the Form Calculation Profile. This expression references field values within an individual feature or in other layers and must return either a date, number, or string value. The referenced expression must be defined in the form template's FormTemplate.expressionInfos. It cannot be set inline within the element object. Field and Group elements must be visible if the field or one of the grouped fields is required.

Example

// Expression created within ExpressionInfos and is referenced in element
const expression = new ExpressionInfo({
  name: "alwaysHidden",
  expression: "false"
});

// Reference an already-defined visibilityExpression set within the ExpressionInfos
const fieldElement = new FieldElement({
  type: "field",
  fieldName: "inspemail",
  label: "Email address",
  visibilityExpression: "alwaysHidden"
});

formTemplate.expressionInfos = [ expression ];
formTemplate.elements = [ fieldElement ];

`toJSON` inherited	`toJSON(): any`	JSONSupportMixin

fromJSON

inheritedstatic Method

Signature: fromJSON (json: any): any

Inherited from: JSONSupportMixin

Creates a new instance of this class and initializes it with values from a JSON object generated from an ArcGIS product. The object passed into the input json parameter often comes from a response to a query operation in the REST API or a toJSON() method from another ArcGIS product. See the Using fromJSON() topic in the Guide for details and examples of when and how to use this function.

Parameters

Parameter	Type	Description	Required
json	`any`	A JSON representation of the instance in the ArcGIS format. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects.

Returns: any
Returns a new instance of this class.

clone

inherited Method

Signature: clone (): this

Inherited from: ClonableMixin

Creates a deep clone of this object. Any properties that store values by reference will be assigned copies of the referenced values on the cloned instance.

Returns: this
A deep clone of the class instance that invoked this method.

toJSON

inherited Method

Signature: toJSON (): any

Inherited from: JSONSupportMixin

Converts an instance of this class to its ArcGIS portal JSON representation. See the Using fromJSON() guide topic for more information.

Returns: any
The ArcGIS portal JSON representation of an instance of this class.
