I have a route with a try .. catch. And in the catch I add a new exception so I go from 1 -> 2 exception. For example I add: java.sql.SqlException.
When I click source tag. The source code is not updated asap.
If I update something else such as the id option, then the source code is updated asap.
So the same thing should happen if I add/remove exceptions.
Also I have seen issues with the properties panel sizing itself. For example if I have 3 exceptions and I click the on the various EIP in my route so the panel changes. When I get back to the doCatch it sometimes dont size / show all the exceptions. So I cant see them all.
