[jira] Commented: (WICKET-1866) MarkupContainer already follows the contract of Iterable; it should implement it.

Igor Vaynberg commented on WICKET-1866:
---------------------------------------

there is a problem with generics here

currently markupcontainer has public Iterator<? extends Component> iterator() but if we make it implement iterable we have to change it to Iterator<Component> ... not sure which one is right.
