Daniele,
If your components auto synchronize (true, by default), then all you would need
to do is add a binding.
MyList.api
- add mySelection binding (when bound, this will cause array to be pushed down
to the subcomponent as well as pushed up from the subcomponent at various times
in request-response cycle)
if MyList does NOT auto synchronize, then you will need to at the least code
push up to parent to have the parent get the value, OR use a shortcut (at least
I know this shortcut is available in the WOD file):
MyList.wod:
Foo : MyList {
mySelection = ^mySelection;
}
Then bind a var in the parent component to the subcomponent
MyPage.wo
- add binding <wo:MyList mySelection=“$myPageMySelection”/>
see:
http://en.wikibooks.org/wiki/WebObjects/Web_Applications/Development/WO_Component/Binding_Synchronization
But in general, pages/components don’t have direct access to subcomponents.
They push/pull values via bindings or share objects whose attributes can be
seen by both component classes.
