The error message tells you everything that you need to know to fix this
First, it indicates that it is looking for an '=' operation accepting a
String argument. The only String-type expression that you have is
'e1.name'. So, the type in which the parser is looking for this
operation (the 'Bag(Operation)' type) must be the target of the '='
operation, that is, 'CallEvent.allInstances().operation'.
You cannot compare a Bag of Operations with a String.
So, you could instead do this:
This will give you the owned operations of 'self' that are called by
*some* behaviour model. It won't ensure that this call is in an
Interaction (rather than, say, an Activity), nor that it is in a
particular interaction, nor *which* call event(s) call which
operation(s). It also doesn't account for inherited operations, if
that's potentially important.
