destroy never triggers

admhemed — Wed, 04 Jul 2018 17:35:30 GMT

Destroy event never ever triggers,

I need this event to know when user removes the visual,

any solution or work around?


module powerbi.extensibility.visual {
    "use strict";

    export class Visual implements IVisual {
        constructor(options: VisualConstructorOptions) {
        }


        public update(options: VisualUpdateOptions) {
        }
        public destroy(): void {
            console.log('%c destroy ', 'background: #222; color: #bada55');
        }
    }
}

This issue is on backlog.

Could you please describe why you need to know when user removes a visual?

I'm saving state for each of my visuals, and I need to know when a user removes the visual to correctly update the state.

Currently I'm using a socket io disconnect event as a work around, but it is not good enough, because the socket disconnects when user refreshes the page for example.

Thanks for the clarification. PBI CV API team will work on this issue but there's no ETA.
