I'm having a very similare problem using BeanEditForm. I have a Date field in
my bean, and when there is no value in this Date field, I'm getting the very
same error. The second problem is, this error does not go awy if I reopen
the page from its starting link - the BeanEditForm is not displayed, but
it's still the error Page. I have to restart Jetty for this error to go
away, strange. I will file an Jira issue for this.
