Pass parameter from one page to another in Freedom UI
To provide some context, I have three objects - A, B and C. Object C acts as a linking object between A and B
Currently, I have a page (object A) with detail (object C) on it. By clicking on "Add" button I open separate page (object C), that contains list (object B) with multiply selection. I need to filter out the records in list, that already exists in detail. After that I need to create records in object C using the selected records from list, along with the passed Id from the page (object A).
So, I have two questions:
1) How can I pass the Id from the page (object A) to page (object C), in order to filter out records in the list.
2) How can I filter out records (object B), that already exists in detail (object C).
I have successfully implemented it in Classic UI, but I'm unable to replicate it in Freedom UI due to the absence of a Sandbox
