AUR0714

This error code has been removed in Aurelia 2.

Status: Removed

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

Previous Error Message

Template compilation error: primary already exists on element/attribute "{{0}}"

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 has been replaced with the defaultProperty option on the custom attribute definition.

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 documentationarrow-up-right for more details.
