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 documentation for more details.
