(Long-time list reader but first post so Hi all!)

I filed a Jira issue earlier today for a similar request regarding WebView/WebEngine navigation - allowing the developer to veto location changes.
Thanks to this discussion I've amended my original idea to match the onCloseRequest approach. <http://javafx-jira.kenai.com/browse/RT-26761>

Love the open flow of ideas in OpenJFX :-)
