Hi,
The usual way is to have a binding in the MyList component that will contain an
array of selected items, you may call it "selectedItems". For the action, is is
better to have also have a binding to create a real reusable component. A
component should never assume it's parent type to be really reusable.
To use a binding for action, you need to disable the auto synchronisation with
this override:
@Override
public boolean synchronizesVariablesWithBindings() {
return false;
}
If the list of items to display come from the parent, you get the value in a
method with valueForBinding("items") for example.
The MyList action method will look like this:
public WOActionResults selectContact() {
setValueForBinding(selectedItems(), "selectedItems"); // Send the
array to parent
return (WOActionResults) valueForBinding(SelectActionBindingName); //
call the parent bound action and return it's result
}
It is quite simple to use, the parent component will look like this:
<wo:MyList action="$itemsSelected" selectedItems="$selectedItems" />
