How can I make one entity attribute change trigger another's default value?

Question

Guys and Gals,
Using JDev 11.1.2.1.0
I have an order form which has a LOV (Customers) and an address field. The address field should contain the default address associated with the selected key in the LOV.
To do this, I have an entity (Order) with two attributes (CustomerID & Address). Address has its default value set to "adf.object.getDefaultAddress" which returns the default address for the CustomerID. This only works on initial load.
How would I make this adf.object.getDefaultAddress trigger when I select a different LOV CustomerID in the View Object?
I've tried various things but am a little confused. Is there something akin to partial triggers for entity objects?
I can provide pictures, code, etc.
Thanks,
Will

Answer 1

you can try this.
go the the setter method in your EntityImpl class for the LOV attribute
public void setCustomerID(Number value) {
        setAttributeInternal(CustomerID, value);
        //here call the setAddress() method
    }in your page, set the customerID autosubmit to true and make the Address field PPR the customer Id.
<af:selectOneChoice value="#{bindings.CustomerID.inputValue}"
                           id="soc1"
                           autoSubmit="true">
        </af:selectOneChoice>
        <af:inputText value="#{bindings.Address.inputValue}"
                               partialTriggers="soc1">
        </af:inputText>
