We are migrating to LEX and moving from solution to articles (rather reluctantly). in our current solution we customised the solution object to add case type, subtype and status fields. When an agent attaches the soltuion then we basically copy the values from the solution onto the case and close it.
In the new world, what I have now found out is that the case article object doesnt support triggers, ok I thought a feed item is created when you attach an article so I can do that, unfortunately the feed item trigger only works on certain types of feed item.
I am trying to find a solution to catch the event of attaching an article to a case can be either in Apex or config I dont care but as of yet I dont see a way to do this without completely building a new Lightning component.
If anyone has managed this I would love to know how
