Custom decorators not working using AoT and Ivy #31495
Description
🐞 bug report
Affected Package
The issue is caused by package @angular/compiler-cli (I guess)Is this a regression?
I had never tried AoT with IvyDescription
I have a custom property decorator like this:export function Language(): PropertyDecorator {
function DecoratorFactory(target: any): void {
const targetNgOnInit: () => void = target.ngOnInit;
function ngOnInit(this: any): void {
// Just for example
console.log('onInit');
if (targetNgOnInit) {
targetNgOnInit.apply(this);
}
}
target.ngOnInit = ngOnInit;
}
return DecoratorFactory;
}
used as:
@Language() lang: string;
ngOnInit() {
// For aot
}
- With AoT compiler, it works (it writes onInit in console)
- If I enable Ivy and disable AoT, it works
- If I enable Ivy and AoT, it doesn't work
🔬 Minimal Reproduction
🔥 Exception or Error
No errors during compilation or in console. The ngOnInit method in decorator function is ignored.
