• In my architecture, I'm using a routing main-component, to switch between sections of my app in which I use single components.

• Also, I have one component in the main-component which stays in 'foreground' all the time and which is needed to be used in combination with the components of the other sections.

• For communication between the 'fixed' component and the other components, I am using a subsciption to the topics of the fixed component.

• Now: when switching through the sections via the routing module, the lifetime of the switchable components is over; their OnDestroy-Methods are getting called (the subscriptions get canceled.)

• When an Event happens, while the other component is not created (which is the case when the user views another route), it can't receive the events.

• In my use case it should be possible to trigger an event in the 'fixed' component, which then triggers the router to be switched to the correct routing-path and get the 'switch'-component-object. This object also needs the information, which the fixed component sent.

• I hope, my explaination is thorough and understandable (also see the attached draft), I'm relatively new to angular and web programming in genereal .

• Now I stumbled upon the Angular RouteReuseStrategy but I'm afraid it won't help, as it kind of 'recreates' a saved state of the before-visited route and the components behind it are 'inactive' and can't receive events either.

Does anyone has a hint for me? Maybe my concept needs a makeover.
