Derived attributes & associations are read-only, but you can also have writable associations that update other attributes or links when they themselves are set.
Read here about how that works on attributes: Derived settable attributes.
OCL for reading Class2selection:
self.Class2
EAL for the writing Class2Selection:
self.Class2 := vInputParameter; self.SelectionLog := self.SelectionLog + DateTime.Now.asString + ': '+ vInputParameter.Name + '\r\n'
The most common use case for this is to execute "extra" code for recalculating other persisted values based on the new value of a change to a link.
