Hi Dan, I'm trying to find whether it is possible to reproduce https://issues.apache.org/jira/browse/ISIS-1224 in the Kitchensink app since I have it setup here. While browsing I noticed that the Hierarchy Objects example behaves strangely: 1) Select "First parent" from the menu 2) Click "Add child" or "Move child" buttons 3) A modal appears with just a label inside - "Child Object". 4) Pressing "OK" in the modal shows an error: 'Child Object' is required. But there is no input field or something to edit a value for the new child.
Maybe I don't use it properly or maybe the form component field is not visible due to the upgrade of Wicket to 7.1.0 here. If it is Wicket 7 then please let me know and I'll debug it. Martin Grigorov Wicket Training and Consulting https://twitter.com/mtgrigorov
