This use case specifically useful for ADF UI value change listener. If there is business logic to be invoked when field value is changed, we can can call ADF BC custom method from assigned value change listener.

What if want to have new value to be available in ADF BC model without passing new value from value change listener as parameter? This is possible if we call processUpdates method in value change listener, before calling custom ADF BC method.
In my example – ADFProcessUpdatesApp.zip, I have created sample method testCall in VO Row implementation class. This method is accessing salary attribute value from current row. I’m going to call this method through bindings from value change listener and lets see what it will print out: Read the complete article here.
