Cant set managed bean property

[Henrique Ordine]

JSF says that my managed bean does not have a setter method for my id property.
But my managed bean class does implements:
Long getId();
void setId(Long);

the problem is, my managed bean class implements an interface which declares this method:
Object getId();

I thought that maybe because getId() in the interface returned Object, JSF might have been looking for a setter method which took an Object.

So I had the managed bean class not implement this interface anymore and it worked fine.

Anybody have any idea why that happens?
