Hi,

I'm calling a existing component using create component and trying to pass attribute for it.
oneController.js

var id='25978371';
        $A.createComponent(
            "c:InDetails",
            {
                oppId: id,
            },
            function(newCmp){
                    component.set("v.currentContent", newCmp);
            }
        );

InDetails.cmp

<aura:attribute name="oppId" type="String"/>

InDetailsController.js

console.log(component.get("v.oppId"))

Indeatails components gets created in component one but console.log of oppId gives me undefined. I couldn't pass the attribute from one component to another.
