Current behavior

Compilation produces the following with strictNullChecks enabled:

Expected behavior

Compilation should not produce any errors.

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

• Angular version: 4.1.0

• Browser: [all | Chrome XX | Firefox XX | IE XX | Safari XX | Mobile Chrome XX | Android X.X Web Browser | iOS XX Safari | iOS XX UIWebView | iOS XX WKWebView ]

• Language: TypeScript 2.2.2

• Node (for AoT issues): node --version = 6.10.2

Could you attach a minimal repro. Thanks.

/cc @mhevery

[sebek64]

I'll try to prepare a repro case today.

[cyrilletuzi]

I confirm this issue, repro is very simple, quite strange it hasn't been spot before release :

• create a new project with Angular CLI
• just add "strictNullChecks": true in tsconfig.json
• ng serve

[mhevery]

This is an issue with TypeScript. Looking for a workaround: microsoft/TypeScript#10078

[afnpires]

As an fyi, the workaround in #16389 PR did not work for me.
Using Typescript 2.3.2 and Angular 4.1.1 still throws the following
