I have two AC-Reactive Reference parameters. The first (A) is an input text box. The second (B) references the value of A and cascades when A-value is changed by user input. However, when A-value is changed programmatically by a javascript function, its value does not cascade to B, even after I force the A-input text box to fire an onchange() event.

The only way to cascade the A-value is for the user to click in the input text box and change something. Upon exit the A.value cascades to parameter B.

An onchange() event in the input text box should cascade the A-value to parameters that reference it.
