Hello,
I have implemented a canvas page in fiori elements according to this blog post: canvas/custom page in List Report application
It's all working fine but I have currently one problem. I am passing a parameter string to the navigateInternal method.

The navigation to the canvas page is working fine but I want to read the key/values from the passed string every time the user navigates to the child page in the child controller to adapt the data! To achieve this I have tried different approaches in the child controller with the onBeforeShow method or attachRouteMatched/attachRoutePatternMatched or with the ExtensionAPI events. As it says here the extensionAPI instance is only accessible in the parent component

I have currently no idea how I can trigger a method in the child controller every time a navigation takes place to adapt the data in the UI. How can I solve this problem?
Thanks!
Best regards,
Dominik
