Composite App Wiring Help Required

I have started looking at Composite Applications for the first time and in the first instance I am hoping to do a simple proof of concept. What I want to do is create an app that does the following:

  • Display users Inbox (no problem);

  • Display users calendar (no problem);

  • Display a view and documents from a supplier database (.nsf, normal Notes app);

  • When a user clicks on an email that is found in the supplier database then the focus of the supplier database CA will change to the selected supplier and in another area of the screen the underlying document will open.

Really struggling to get started with the overall wiring and linking required. The email address in the mail file is ultimately what needs to link the other CA’s together.

Any suggestions on how I approach this?

Thanks
