Angular 5: Completion and Nav to Declaration on custom directives with binding () or []

Binding work correctly for me:

can yu check if the issue persists after invalidating caches (File | Invalidate caches, Invalidate and restart)? Also, does the other angular stuff work? I.e, are the standard directives, etc. recognized?

Sorry, apparently I can't write a post title.  My post was about directives In spite of what it said in the title (fixed). You are looking at a component, selected, by element name "my-hero-detail", I presume.  I'm guessing that since is not embedded in binding syntax, () or [], it doesn't have that problem.   

That said, I tried invalidating the cache, as you suggest.  It made no difference. 

Standard directives are recognized (e.g. click), sort of.  They don't highlight as identifiers elsewhere, but I can navigate to a core.scripting.rnc. that is in the idea.jar.  

please share a sample project/files i can use to recreate the issue;

Create a brand new angular-cli project, then add:

Directive: my-test-directive.ts:

import {AfterViewInit, Directive, EventEmitter, Output} from '@angular/core';
@Directive({
  selector: '[appMyTest]'
})
export class MyTestDirective implements AfterViewInit {
  @Output() appMyTest= new EventEmitter<void>();
  constructor() { }
  ngAfterViewInit() { this.appMyTest.emit(); }
}

Add this to an app.component.html:

<div (appMyTest)="logme()" ></div>

Add this to app.component.ts, in class AppComponent :

logme() { console.log('here i am')   }

You will find that:

In app.component.html,  on "appMyTest" 

• IntelliJ does not allow for code completion within the parens (e.g. remove the MyTest from appMyTest, you get: No suggestions).
• IntelliJ does not navigate to the directive. Ctrl-B goes to the beginning of the div.

In my-test-directive.ts, on MyTestDirective find usages (Ctrl-B, again) does not identify app.component.html as one of the usages.

However, if I add a redundant appMyTest:

<div appMyTest (appMyTest)="logme()" ></div>

then all works as expected However, it is ugly at best and might have some weird results in the template compiler at worst..

Regarding WEB-27874, I do get an autocomplete when typing outside of the parens but the complete gives 

appMyTest=""

rather than: 

(appMyTest)=""

But that's minor.  I'm more concerned about the navigation/usage.  Also, if the directive has another input, without the redundant name, there's a warning: Attribute attributeName is not allowed here.

If you need more, let me know where I can share a project, but this is pretty simple.
