AUR0714

Status: Removed

This error code has been removed from Aurelia 2. The primary property on bindable definitions no longer exists.

Previous Error Message

AUR0714: Template compilation error: primary already exists on element/attribute "<name>"

Migration

In previous versions of Aurelia 2, you could mark a bindable property as primary: true to indicate which property should receive values when using shorthand syntax. This could cause conflicts if multiple bindables were marked as primary.

This has been replaced with the defaultProperty option on the custom attribute definition, which is a single string property that cannot conflict.

Old API (no longer supported):

import { bindable, customAttribute } from 'aurelia';

@customAttribute('my-attr')
export class MyAttribute {
  @bindable({ primary: true }) value: string;
  @bindable other: string;
}

New API:

import { bindable, customAttribute } from 'aurelia';

@customAttribute({ name: 'my-attr', defaultProperty: 'value' })
export class MyAttribute {
  @bindable value: string;
  @bindable other: string;
}

The defaultProperty option specifies which property receives the value when the attribute is used with shorthand syntax. If not specified, it defaults to 'value'.

See the Custom Attributes documentation for more details.
