Fiori Elements Navigation to Canvas page event

[dommeyer]

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

In the Component.js file of your custom component, you need to define the fields in the metadata:

metadata: {  
			manifest: "json",
			properties: {
				<importing_fieldname1>: {
					type: "string",
					group: "standard",
					defaultValue: null
				},
				<importing_fieldname2>: {
					type: "string",
					group: "standard",
					defaultValue: null
				}
			}
		},
