Hello Sven, sorry for delay Here is the quick-start: https://github.com/solomax/form-null-value.git To reproduce the issue 1) mvn jetty:run 2) go to http://localhost:8080 3) Click "Reset"
Everything will work as expected if 1) wicket version is set to M8 2) any value is selected in drop down before clicking reset Will continue debugging ...
