Ivy: Should not combine @Input decorators and query decorators

See original GitHub issue

🐞 bug report

Affected Package

@angular/compiler-cli (8.1 rc0)

Is this a regression?

No, same result without Ivy.

Description

With Ivy @Inputdecorators shouldn’t be combined with query decorators such as @ViewChild ( #31056 )

🔬 Minimal Reproduction

https://github.com/hugodes/repro-decorators

🔥 Exception or Error

@istiti you’re 100% right 🎯. We had aot set to true on our internal project. Never thought to update to aot::true on my repro-repo !

Thank you so much for your time !

Ok, I updated my comment and I see your problem please enable aot:true

To understand the problem in JIT (aot:false like you have) no angular compiler is used to proceed your ts files; tsc is used directly, CLI cannot emit you error in console.

But when you set aot:true angular compiler is used and CLI can throw error you see at runtime.

I admit in little project we can see problem quickly but in large project runtime errors are dangerous! But in v8.1 aot is enabled by default with IVY and should solve the problem.
