When I load the page first time, on some pages it shows unsubscribe error in ngOnDestroy as I am unsubscribing subscribes in it. I am not sure why ngOnDestroy is called at the init of the component. This is the error what I see when the page is first loaded. I thought this was some issue from angular2-multiselect-dropdown but in some other component, its own ngOnDestory is called as well and says subscription to unsubscribe is not defined. So I added if condition to remove the error message. This is the creation of the subscription. Actually I don't think it has any other problem in defining the observable. So is this a problem with angular component lifecycle or possibly an issue from angular2-multiselect-dropdown? I didn't see this error before and not sure what I did wrong. Can anyone had similar issue or help me on this? Thanks in advance. Continue reading...
