The feature form definition used to define the user interface for the form.
A description of the form.
An ordered list of the elements contained by the form.
The feature displayed in the form.
If true, the value for a previously visible FieldFormElement is retained when it (or its parent) is hidden. The default is false, meaning the value is cleared when an element is hidden.
A dictionary mapping from FieldFormElement.fieldName to an array of errors. An empty dictionary indicates that all element's values are valid. Constraints are expressed by the FormInput and the value of FieldFormElement.isRequired of the element. The constraints depend on the type of FormInput. The errors returned for each key is an array of any of the following types:
Functions
Discards edits to FeatureForm.elements and their associated Feature.attributes. Edits are discarded but the Feature is not refreshed. Values will be reset to the values at the time of FeatureForm creation.
Asynchronously evaluates all form expressions. An expression can include Arcade FeatureSet functions, which need to be evaluated asynchronously. Upon completion the task provides a set of FormExpressionEvaluationError providing diagnostic information about errors encountered during evaluation of expressions. An empty list indicates no errors were encountered.
