Ok reproduced.

The MyAgClickableParentComponentSchema break the parsing. Will try to resolve that asap.

compodoc/src/app/compiler/dependencies.ts

Line 1184 in aee4a24

var properties = decorator.expression.arguments[0].properties;

Normally decorator.expression.arguments[0] was an instance of NodeObject, but in this case IdentifierObject.

[AilisObrian]

It called by

compodoc/src/app/compiler/dependencies.ts

Line 1266 in aee4a24

directiveInfo = this.visitDirectiveDecorator(classDeclaration.decorators[i]);

directiveInfo = this.visitDirectiveDecorator(classDeclaration.decorators[i]);

But I couldn't find the usage of directiveInfo.
Is there any hint of this?

[AilisObrian]

Is it possible to get the not-yet parsed variable (MyAgClickableParentComponentSchema) from this.visitDirectiveDecorator()?

[vogloblinsky]

@AilisObrian not yet done the test, may be.

I also get the same error when running compodoc

Hi, this also happens when you try to extend your decorator with spread (...) operator.

For example:

base.ts

import { trigger, state, transition, animate, style } from "@angular/animations";

export const DECORATIONS_BASE = {
     styles:[':host{position:static;display:block;height: auto; width: auto;}'],
     animations: [
        trigger('shownChanged', [
        state("SHOWN_STATE", style({ opacity: 1 })), 
        state("HIDDEN_STATE", style({ opacity: 0 })),
        transition('* => *', animate('.2s'))
        ])
    ]
};

comp.component.ts

import { Component, OnInit } from '@angular/core';
import {DECORATIONS_BASE} from './base';


@Component({
  selector: 'my-comp',
  templateUrl: './comp.component.html',
  styleUrls: [ './comp.component.css' ],
  ...DECORATIONS_BASE
})
// export class YourComponentClassName

Hope it's possible to fix.

Thank you!
