How to set default value to Drop Down in EntityCombinedScreen

Support
#1

I am trying to set default value for dropdown with create action in EntityCombinedScreen

#2

What drop-down? Please explain your problem.

#3

When I click the create button, set default value to lookupfield which are available in lookupfield options in Entity Combined Screen.

#4 
@Inject
private LookupField myField;

protected void enableEditControls(boolean creating) {
super(creating);
    if (creating) {
        myField.setValue(someValue);
    }  
}

But better initialize the new entity:

@Override
protected void initNewItem(Entity item) {
    MyEntity entity = (MyEntity) item;
    entity.setSomething(someValue);
}
