Wouldn't it be better design-wise to factor out this functionality
into some helper object? Then in the child you could bind to a getter
that relies upon this helper - and the parent does the same.
Just thinking loud

Seabix,
Wouldn't using performParentAction() from a subcomponent invoke an
action and subsequently create a new request-response loop? I
don't really think that's what you're after.
It seems to me that you really want an instance variable in the
parent that you would access from the subcomponent through key
value coding. Put your calculation in the getter method so KVC
will access its return value through your bound key.
Maybe the ^value1ModifiedByParent binding syntax would work for
your. Otherwise you could also use a backing instance variable
inside your subcomponent that binds directly to the instance
variable in the parent component.
This is just off the top of my head, but seems like a more logical
solution.

Is it possible to do the following? How?
ParentComponent - Parent.wo
ChildComponent - Child.wo
There is a WORepetiotion in Child.woa with a bunch of String
values. So the
WORepetition is bound to the NSArray listValues and to the String
value.
No i wan't to give the value of each iteration up to the parent
where an
action (public String modifyChildValue()) is performed and the
return value
will show up next to the original value in the WORepetition (in
Child.wo).
The Result would be something like this:
Value1 - Value1ModifiedByParent
Value2 - Value2ModifiedByParent
Value3 - Value3ModifiedByParent
Can anyone help me on this?
Thanks.
