Can not use Property Decorator in mixin (Decorators are not valid here)

[jogibear9988]

I've a mixin like this

type Constructor<T> = { new (...args: any[]): T };

function VisuElement<B extends Constructor<any>>(base: B) {
    return class extends base {
     constructor(...args: any[]) {
         super();
         this._ve = true;
         this._veBindings = [];
     }

    static get properties() {
        return {
            unbindOnUnload: Boolean //Needed when a Element is created via a Dom repeat
        }

here it is not possible to replace static get properties() with decorator. => "Decorators are not valid here"

This is not an issue with the project but a limitation of TypeScript.

You need to name the class and return that instead:

function VisuElement<B extends Constructor<any>>(base: B) {
    class Mixin extends base { }

    return Mixin
}
