What is "customers" used in Declarative creation method.


I am using declarative creation method.

public void init(Map<String, Object> params) {
    Set<Customer> entities = (Set<Customer>) params.get("customers");
    for (Customer entity : entities) {

Can any one say me what is “customers” used in params.get(“customers”). Because I am getting null value for entities in this example.


I don’t know what example you are talking about, but “customers” here should be a screen parameter passed when the screen is opened. See a working example here in the ProductBrowse screen.
