I have in my JSF 2.2 page an event listener in the <f:metadata> and its preRenderView is not working on every page call, it's only working for the first page load and when I use the add() method the lists refreshes at shows the added line, but I can't get it to work for my delete() method at all, nothing gets deleted and the view doesn't refresh either.
But everything works fine if I ignore the meta tag and just load the list in the getListe() method, but I shouldn't put business code in the getter.
