Creating and rising an event is not complicated at all in Fabric composer. You need the following steps:
1. Define your event in the mode file
event MyEvent {
o <type> Property1
o <type> Property2
}
2. Create your event in the your transaction javascript logic.
let myEvent = await getFactory().newEvent(namespace, 'MyEvent');
3. Filling the event properties:
MyEvent.Property1 = <value1>;
MyEvent.Property2 = <value2>;
emit(MyEvent);
