Binding - Trigger Parameter to Property
To understand how this particular binding concept works, consider the following scenario.
IntuiFace generates a random number and then asks the user to guess it by selecting a corresponding onscreen item. To determine whether the correct item was selected, the following trigger is used: "When [the randomly generated number] is selected, then [do something]." The trigger parameter "[the randomly generated number]" gets its value, through binding, from the Result property of the Random From List Interface Asset.

Properties can be bound from/to any other property, regardless of type - e.g. integer, string, true/false. IntuiFace does not verify if properties are compatible. Beware of weird behavior if you bind properties of different types.
