a quick background first: I'm creating a component which can display a 'list
of lists'. For flexibility I want to implement this as a composite-pattern
in which a CompositeFlexList-component can render one or more
FlexList-components as it's childs. (CompositeFlexList extends FlexList).
This works well when I define the list-component as @Component in the
CompositeFlexList-component.
However for flexibility I need to extract the FlexList-component-definition
from the CompositeFlexList-component and define it in an enclosing page.
So want i want is this:
page
|[EMAIL PROTECTED](..some config here.....,childlist=childlist)
CompositeFlexList
list;
|[EMAIL PROTECTED](some config here....) FlexList childlist;
Now CompositeFlexList has the following definition:
@Parameter
private FlexList childlist;
public FlexList getChildlist() {return childlist;}
My problem/question:
although component childlist is entirely defined in the enclosing page, and
this component is bound (???) to field childlist in the CompositeFlexList I
keep getting an "unbound error", see below.
Am I missing something, or is it impossible to pass a defined
component-instance as a parameter to another component?
Thanks in advance,
Geert-Jan
