Your outter bean should already have a reference to it when the getter
is called. The EventBean stuff doesn't re-set a bean using a setter
after getting it from the outter bean because CFCs are passed by
reference and there is no need to do that. When you create the new inner
bean, you have to stash a reference to it in the outter bean before
returning it from the getter.
Looks like your getter for it does not abide by that contract so a new
ExtraData is created but not assigned to any variable (i.e. the CFC this
scope) and therefore is transient / orphaned. It should look something
like this:
public function getExtraData(){
if(isNull(this.extraData)){
this.extraData = new extraData();
}
return this.extraData;
}
The CFML and Java standard with beans is that you don't have to re-set
data that is passed by reference to setter when you've gotten it from
the getter. It's really up to the target CFC you are calling the getter
in if that CFC needs to hold a reference to that object being created.
